CROSS REFERENCE TO RELATED APPLICATIONS 
     This application claims the benefit of priority to Japanese Patent Application No. 2017-236342 filed on Dec. 8, 2017. The entire contents of this application are hereby incorporated herein by reference. 
     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a multilayer ceramic electronic component, and particularly, to a multilayer ceramic electronic component suitable for a high withstand voltage. 
     2. Description of the Related Art 
     In recent years, miniaturization and high capacitance of a multilayer ceramic capacitor is advancing due to miniaturization and surface mounting of an electronic device. Such a trend also spreads to medium and high voltage capacitors for a backlight and a switching power supply of a liquid crystal display. Thus, in the field of high-withstand voltage multilayer ceramic capacitor, there is also a demand for a smaller and high-capacitance multilayer ceramic capacitor. 
     For example, the method described in Japanese Patent Application Laid-Open No. 2003-272946 has been proposed as a method for increasing the withstand voltage. In the method of Japanese Patent Application Laid-Open No. 2003-272946, as illustrated in  FIGS. 33A to 33C , an internal electrode  4  connected to external electrodes  3  opposed to each other at both ends of a laminated body  2  made of a dielectric are divided into a plurality of pieces, and adjacent internal electrodes  5  are formed with a dielectric layer interposed therebetween so as to overlap both sides of the divided portion. At this point, the internal electrode  5  is not connected to the external electrode  3 . 
     By adopting this structure, a capacitor is formed in a portion in which the internal electrode  4  and the internal electrode  5  are opposed to each other. Thus, a plurality of capacitors are formed between the external electrodes  3  opposed to each other, and the capacitors are connected in series. For this reason, voltage applied to each capacitor is decreased, so that the internal withstand voltage of the laminated body  2  is able to be increased. 
     However, in order to obtain the higher withstand voltage, it is necessary to increase the number of divided internal electrodes and to increase the number of opposed portions of the internal electrodes (to increase the number of capacitors connected in series). However, there is a limit to the high withstand voltage design within a range of the standard dimensions of the multilayer ceramic capacitor. This is because when the number of divided internal electrodes is increased to increase the number of the opposing portions of the internal electrodes, an effective area of the opposing portion of the internal electrodes is reduced, and the electrostatic capacitance is difficult to acquire. 
     It is conceivable as a countermeasure against the above-described problem to mount a plurality of multilayer ceramic capacitors having a structure in which the number of opposing portions of the internal electrodes is increased, on the mounting substrate. However, in this case, the mounting area becomes large as the number of multilayer ceramic capacitors is increased.

In this case, the first external electrode  34   a  is electrically connected to the first extended electrode portion  30   a  of the first internal electrode  28   a . Alternatively, the first external electrode  34   a  may be disposed only on the surface of the first end surface  24   e  of the first laminated body  24 . 
     The second external electrode  34   b  is disposed on the surface of the second end surface  24   f  of the first laminated body  24 , extends from the second end surface  24   f , and covers the first main surface  24   a , the second main surface  24   b , the first side surface  24   c , and the second side surface  24   d . In this case, the second external electrode  34   b  is electrically connected to the second extended electrode portion  30   b  of the second internal electrode  28   b . Alternatively, the second external electrode  34   b  may be disposed only on the surface of the second end surface  24   f  of the first laminated body  24 . 
     In the case in which the first multilayer ceramic electronic component body  12  is a capacitor, in the first laminated body  24 , the first internal electrode  28   a  and the second internal electrode  28   b  are opposed to each other with the dielectric layer  26  interposed therebetween in each opposed electrode portion  32   a , thus producing the electrostatic capacitance. For this reason, the electrostatic capacitance is able to be obtained between the first external electrode  34   a  to which the first internal electrode  28   a  is connected and the second external electrode  34   b  to which the second internal electrode  28   b  is connected. That is, the first multilayer ceramic electronic component body  12  includes one capacitor in the first laminated body  24 . 
     As illustrated in  FIG. 6 , the first external electrode  34   a  includes a first underlying electrode layer  38   a  and a first plating layer  40   a  disposed on the surface of the first underlying electrode layer  38   a  in order from the side of the first laminated body  24 . Similarly, the second external electrode  34   b  includes a second underlying electrode layer  38   b  and a second plating layer  40   b  disposed on the surface of the second underlying electrode layer  38   b  in order from the side of the first laminated body  24 . 
     The first underlying electrode layer  38   a  is disposed on the surface of the first end surface  24   e  of the first laminated body  24 , extends from the first end surface  24   e , and covers a portion of each of the first main surface  24   a , the second main surface  24   b , the first side surface  24   c , and the second side surface  24   d . Alternatively, the first underlying electrode layer  38   a  may be disposed only on the surface of the first end surface  24   e  of the first laminated body  24 . 
     The second underlying electrode layer  38   b  is disposed on the surface of the second end surface  24   f  of the first laminated body  24 , extends from the second end surface  24   f , and covers a portion of each of the first main surface  24   a , the second main surface  24   b , the first side surface  24   c , and the second side surface  24   d . Alternatively, the second underlying electrode layer  38   b  may be disposed only on the surface of the second end surface  24   f  of the first laminated body  24 . 
     Each of the first underlying electrode layer  38   a  and the second underlying electrode layer  38   b  (hereinafter, also simply referred to as underlying electrode layer) preferably includes, for example, at least one selected from a baking layer, a resin layer, and a thin film layer. In the first preferred embodiment, the first underlying electrode layer  38   a  and the second underlying electrode layer  38   b , which are defined by the baking layer, will be described. 
     The baking layer includes glass and metal. For example, the metal of the baking layer preferably includes at least one selected from Cu, Ni, Ag, Pb, Ag—Pb alloy, and Au. The glass of the baking layer preferably includes at least one selected from B, Si, Ba, Mg, Al, and Li, for example. A plurality of baking layers may be provided. A conductive paste including glass and metal is applied to the first laminated body  24 , and baked to form the baking layer. The baking layer may be formed at the same time as the dielectric layer  26  and the internal electrode are fired, or the baking layer may be formed after the dielectric layer  26  and the internal electrode  28  are fired. Preferably, the thickness of the thickest portion of the baking layer is in a range from about 10 μm to about 50 μm, for example. 
     A resin layer preferably including conductive particles and a thermosetting resin, for example, may be provided on the surface of the baking layer. The resin layer may be directly provided on the first laminated body  24  without providing the baking layer. A plurality of resin layers may be provided. Preferably, the thickness of the thickest portion of the resin layer is in a range from about 20 μm to about 150 μm, for example.

     The first plating layer  40   a  is disposed on the surface of the first underlying electrode layer  38   a  so as to cover the first underlying electrode layer  38   a . Similarly, the second plating layer  40   b  is disposed on the surface of the second underlying electrode layer  38   b  so as to cover the second underlying electrode layer  38   b.    
     For example, at least one metal selected from Cu, Ni, Sn, Ag, Pd, Ag—Pd alloy, and Au or an alloy including the selected metal is preferably used as the first plating layer  40   a  and the second plating layer  40   b  (hereinafter, also simply referred to as plating layer). 
     A plurality of plating layers may be provided. In this case, preferably the plating layer has a two-layer structure of an Ni plating layer and an Sn plating layer, for example. The Ni plating layer covers the surface of the underlying electrode layer, which prevents the underlying electrode layer from being eroded by solder in mounting the multilayer ceramic electronic component  10 A on a mounting substrate. By providing the Sn plating layer on the surface of the Ni plating layer, wettability of solder is improved to easily mount the multilayer ceramic electronic component  10 A. 
     Preferably, the thickness per layer of the plating layer is in a range of about 1 μm to about 20 μm, for example. Preferably, the plating layer does not include glass. Preferably, in the plating layer, a ratio of metal per unit volume is greater than or equal to about 99 vol %, for example. 
     The case in which the first underlying electrode layer  38   a  and the second underlying electrode layer  38   b  are defined by a plating electrode will be described below. The first underlying electrode layer  38   a  is defined by a plating layer directly connected to the internal electrode  28 , is directly disposed on the surface of the first end surface  24   e  of the first laminated body  24 , extends from the first end surface  24   e , and covers a portion of each of the first main surface  24   a , the second main surface  24   b , the first side surface  24   c , and the second side surface  24   d.

     However, a catalyst is provided on the first laminated body  24  as a pretreatment in order that the first underlying electrode layer  38   a  and the second underlying electrode layer  38   b  are defined by the plating layer. 
     Preferably, the first underlying electrode layer  38   a  defined by the plating layer is covered with the first plating layer  40   a . Similarly, preferably, the second underlying electrode layer  38   b  defined by the plating layer is covered with the second plating layer  40   b.    
     Preferably, for example, the first underlying electrode layer  38   a , the second underlying electrode layer  38   b , the first plating layer  40   a , and the second plating layer  40   b  include at least one metal selected from Cu, Ni, Sn, Pb, Au, Ag, Pd, Bi, and Zn or an alloy including the selected metal. 
     The first plating layer  40   a  and the second plating layer  40   b  are provided as necessary, and the first external electrode  34   a  may be defined by only the first underlying electrode layer  38   a , and the second external electrode  34   b  may be defined by only the second underlying electrode layer  38   b .

     A first multilayer ceramic electronic component body  112  in  FIG. 9  is provided as another example of the first multilayer ceramic electronic component body  12  according to a preferred embodiment in  FIG. 1 . The structure of the first multilayer ceramic electronic component body  112  is the same as or similar to that of the first multilayer ceramic electronic component body  12 , except for the internal electrode. Thus, the same or similar portions as those of the first laminated ceramic electronic component body  12  are denoted by the same reference numerals, and the description thereof is omitted. 
       FIG. 9  is an external perspective view of the multilayer ceramic electronic component body  112 .  FIG. 10  is a cross-sectional view taken along line X-X in  FIG. 9 .  FIG. 11  is a cross-sectional view taken along line XI-XI in  FIG. 9 .  FIG. 12  is a cross-sectional view taken along line XII-XII in  FIG. 10 .  FIG. 13  is a cross-sectional view taken along line XIII-XIII in  FIG. 10 . 
     The first multilayer ceramic electronic component body  112  includes two capacitors connected in series in the first laminated body  24 . 
     As illustrated in  FIG. 10 , the first laminated body  24  of the first multilayer ceramic electronic component body  112  includes a fifth internal electrode  128   a  connected to the first external electrode  34   a , a sixth internal electrode  128   b , which is located on the same dielectric layer  26  as the fifth internal electrode  128   a  and connected to the second external electrode  34   b  while being spaced away from the fifth internal electrode  128   a  by a predetermined interval  132   d , and a seventh internal electrode  128   c , which is located on a dielectric layer  26  different from the dielectric layer  26  on which the fifth internal electrode  128   a  and the sixth internal electrode  128   b  are located. The fifth internal electrode  128   a , the sixth internal electrode  128   b , and the seventh internal electrode  128   c  are buried so as to be alternately arranged at equal or substantially equal intervals along the lamination direction x of the first laminated body  24 . 
     A fifth extended electrode portion  130   a  led out to the first end surface  24   e  of the first laminated body  24  is provided on one end side of the fifth internal electrode  128   a . A sixth extended electrode portion  130   b  led out to the second end surface  24   f  of the first laminated body  24  is provided on one end side of the sixth internal electrode  128   b . Specifically, the fifth extended electrode portion  130   a  on one end side of the fifth internal electrode  128   a  is exposed on the first end surface  24   e  of the first laminated body  24 , and connected to the first external electrode  34   a . The sixth extended electrode portion  130   b  on one end side of the sixth internal electrode  128   b  is exposed on the second end surface  24   f  of the first laminated body  24 , and connected to the second external electrode  34   b.    
     The seventh internal electrode  128   c  does not include an extended electrode portion, and is not exposed on the surface of the first laminated body  24 . Thus, the seventh internal electrode  128   c  is connected to neither the first external electrode  34   a  nor the second external electrode  34   b.    
     The seventh internal electrode  128   c  is opposed to a portion of the fifth internal electrode  128   a  and a portion of the sixth internal electrode  128   b . That is, in the first laminated body  24 , opposed electrode portions  132   a  are provided in a portion in which a portion of the fifth internal electrode  128   a  is opposed to the seventh internal electrode  128   c  with the dielectric layer  26  interposed therebetween and a portion in which a portion of the sixth internal electrode  128   b  is opposed to the seventh internal electrode  128   c  with the dielectric layer  26  interposed therebetween. In the case in which the first multilayer ceramic electronic component body  112  is a capacitor, the electrostatic capacitance is produced in each of the two opposed electrode portions  132   a.    
     The first laminated body  24  includes W gaps  132   b  between one end in the width direction y of the opposed electrode portion  132   a  and the first side surface  24   c  and between the other end in the width direction y of the opposed electrode portion  132   a  and the second side surface  24   d . The first laminated body  24  includes L gaps  132   c  between one end of the seventh internal electrode  128   c  and the first end surface  24   e  and between the other end of the seventh internal electrode  128   c  and the second end surface  24   f.    
     In the first laminated body  24 , the internal electrode  128  may be disposed so as to be parallel or substantially parallel to the sheet-shaped insulator  22  (opposed to the insulator  22 ), or the internal electrode  128  may be disposed so as to be orthogonal or substantially orthogonal to the insulator  22 . 
     In the case in which the first multilayer ceramic electronic component body  112  is a capacitor, in the first laminated body  24 , in each opposed electrode portion  132   a , the fifth internal electrode  128   a  and the seventh internal electrode  128   c  are opposed to each other with the dielectric layer  26  interposed therebetween, and the sixth internal electrode  128   b  and the seventh internal electrode  128   c  are opposed to each other with the dielectric layer  26  interposed therebetween, thus producing the electrostatic capacitance. Consequently, in the first multilayer ceramic electronic component body  112 , the two capacitors are connected in series between the first external electrode  34   a  and the second external electrode  34   b . For this reason, the voltage applied to each capacitor is decreased, so that the internal withstand voltage is able to be further increased. 
     A first multilayer ceramic electronic component body  212  in  FIG. 14  is provided as still another example of the first multilayer ceramic electronic component body  12  in  FIG. 1 . The structure of the first multilayer ceramic electronic component body  212  is the same as or similar to that of the first multilayer ceramic electronic component body  12 , except for the internal electrode. Thus, the same as or similar portions as those of the first laminated ceramic electronic component body  12  are denoted by the same reference numerals, and the description thereof is omitted. 
       FIG. 14  is an external perspective view illustrating the multilayer ceramic electronic component body  212 .  FIG. 15  is a cross-sectional view taken along line XV-XV in  FIG. 14 .  FIG. 16  is a cross-sectional view taken along line XVI-XVI in  FIG. 14 .  FIG. 17  is a cross-sectional view taken along line XVII-XVII in  FIG. 15 .  FIG. 18  is a cross-sectional view taken along line XVIII-XVIII in  FIG. 15 . 
     The first multilayer ceramic electronic component body  212  includes at least three and odd-numbered capacitors that are connected in series in the first laminated body  24 . 
     As illustrated in  FIG. 15 , the first laminated body  24  of the first multilayer ceramic electronic component body  212  includes an eleventh internal electrode  228   a  connected to the first external electrode  34   a , a twelfth internal electrode  228   b  on a dielectric layer  26  different from the dielectric layer  26  on which the eleventh internal electrode  228   a  is located and connected to the second external electrode  34   b , at least one thirteenth internal electrode  228   c  on the same dielectric layer  26  as the eleventh internal electrode  228   a  and spaced away from the eleventh internal electrode  228   a  by a predetermined interval  232   d , and at least one fourteenth internal electrode  228   d  on the same dielectric layer  26  as the twelfth internal electrode  228   b  and spaced away from the twelfth internal electrode  228   b  by the predetermined interval  232   d.    
     In the case in which at least two thirteenth internal electrodes  228   c  are provided, the thirteenth internal electrodes  228   c  are provided on the same dielectric layer  26  at the predetermined interval  232   d  with the adjacent thirteenth internal electrode  228   c  in the direction connecting the first external electrode  34   a  and the second external electrode  34   b.    
     Similarly, in the case in which at least two fourteenth internal electrodes  228   d  are provided, the fourteenth internal electrodes  228   d  are provided on the same dielectric layer  26  at the predetermined interval  232   d  with the adjacent fourteenth internal electrode  228   d  in the direction connecting the first external electrode  34   a  and the second external electrode  34   b.    
     The thirteenth internal electrode  228   c  is opposed to any two of a portion of the twelfth internal electrode  228   b , a portion of the fourteenth internal electrode  228   d , and a portion of another fourteenth internal electrode  228   d , and the fourteenth internal electrode  228   d  is opposed to any two of a portion of the eleventh internal electrode  228   a , a portion of the thirteenth internal electrode  228   c , and a portion of another thirteenth internal electrode  228   c.    
     The case in which the first multilayer ceramic electronic component body  212  includes three capacitors that are connected in series in the first laminated body  24  will be described below as an example. 
     An eleventh extended electrode portion  230   a  led out to the first end surface  24   e  of the first laminated body  24  is provided on one end side of the eleventh internal electrode  228   a . A twelfth extended electrode portion  230   b  led out to the second end surface  24   f  of the first laminated body  24  is provided on one end side of the twelfth internal electrode  228   b . Specifically, the eleventh extended electrode portion  230   a  on one end side of the eleventh internal electrode  228   a  is exposed on the first end surface  24   e  of the first laminated body  24 , and connected to the first external electrode  34   a . The twelfth extended electrode portion  230   b  on one end side of the twelfth internal electrode  228   b  is exposed on the second end surface  24   f  of the first laminated body  24 , and connected to the second external electrode  34   b.    
     On the other hand, the thirteenth internal electrode  228   c  and the fourteenth internal electrode  228   d  do not include an extended electrode portion, and are not exposed on the surface of the first laminated body  24 . Thus, the thirteenth internal electrode  228   c  and the fourteenth internal electrode  228   d  are connected to neither the first external electrode  34   a  nor the second external electrode  34   b.    
     The thirteenth internal electrode  228   c  is opposed to a portion of the twelfth internal electrode  228   b  and a portion of the fourteenth internal electrode  228   d . The fourteenth internal electrode  228   d  is opposed to a portion of the eleventh internal electrode  228   a  and a portion of the thirteenth internal electrode  228   c . That is, the first laminated body  24  includes opposed electrode portions  232   a  in a portion in which a portion of the eleventh internal electrode  228   a  is opposed to the fourteenth internal electrode  228   d  with the dielectric layer  26  interposed therebetween, a portion in which a portion of the thirteenth internal electrode  228   c  is opposed to a portion of the fourteenth internal electrode  228   d  with the dielectric layer  26  interposed therebetween, and a portion in which a portion of the twelfth internal electrode  228   b  is opposed to the thirteenth internal electrode  228   c  with the dielectric layer  26  interposed therebetween. In the case in which the first multilayer ceramic electronic component body  212  is a capacitor, the electrostatic capacitance is produced in each of the three opposed electrode portions  232   a.    
     The first laminated body  24  includes W gaps  232   b  between one end in the width direction y of the opposed electrode portion  232   a  and the first side surface  24   c  and between the other end in the width direction y of the opposed electrode portion  232   a  and the second side surface  24   d . The first laminated body  24  includes the intervals  232   d  between a leading end of the eleventh internal electrode  228   a  and one end of the thirteenth internal electrode  228   c  and between a leading end of the twelfth internal electrode  228   b  and one end of the fourteenth internal electrode  228   d . The first laminated body  24  includes L gaps  232   c  between the other end of the thirteenth internal electrode  228   c  and the second end surface  24   f  and between the other end of the fourteenth internal electrode  228   d  and the first end surface  24   e.    
     In the first laminated body  24 , the internal electrode  228  may be disposed so as to be parallel or substantially parallel to the sheet-shaped insulator  22  (opposed to the insulator  22 ), or the internal electrode  228  may be disposed so as to be orthogonal or substantially orthogonal to the insulator  22 . 
     In the case in which the first multilayer ceramic electronic component body  212  is a capacitor, in the first laminated body  24 , in each opposed electrode portion  232   a , the eleventh internal electrode  228   a  and the fourteenth internal electrode  228   d  are opposed to each other with the dielectric layer interposed therebetween, the thirteenth internal electrode  228   c  and the fourteenth internal electrode  228   d  are opposed to each other with the dielectric layer  26  interposed therebetween, and the twelfth internal electrode  228   b  and the thirteenth internal electrode  228   c  are opposed to each other with the dielectric layer  26  interposed therebetween, thus producing the electrostatic capacitance. Consequently, in the first multilayer ceramic electronic component body  212 , the three capacitors are connected in series between the first external electrode  34   a  and the second external electrode  34   b . For this reason, the voltage applied to each capacitor is decreased, so that the internal withstand voltage is able to be further increased. 
     A first multilayer ceramic electronic component body  312  in  FIG. 19  is provided as a yet another example of the first multilayer ceramic electronic component body  12  in  FIG. 1 . The structure of the first multilayer ceramic electronic component body  312  is the same as or similar to that of the first multilayer ceramic electronic component body  12  except for the internal electrode. Thus, the same or similar portions as those of the first laminated ceramic electronic component body  12  are denoted by the same reference numerals, and the description thereof is omitted.

     The first multilayer ceramic electronic component body  312  includes at least four and even-numbered capacitors that are connected in series in the first laminated body  24 . 
     As illustrated in  FIG. 20 , the first laminated body  24  of the first multilayer ceramic electronic component body  312  includes a nineteenth internal electrode  328   a  connected to the first external electrode  34   a , a twentieth internal electrode  328   b  on the same dielectric layer  26  as the nineteenth internal electrode  328   a  and connected to the second external electrode  34   b , at least one twenty-first internal electrode  328   c  on the same dielectric layer  26  as the nineteenth internal electrode  328   a  and twentieth internal electrode  328   b  and separated between the nineteenth internal electrode  328   a  and the twentieth internal electrode  328   b  at a predetermined interval  332   d , and at least two twenty-second internal electrodes  328   d  on a dielectric layer  26  different from the dielectric layer  26  on which the nineteenth internal electrode  328   a  and the twentieth internal electrode  328   b  are located. 
     In the case in which at least two twenty-first internal electrodes  328   c  are provided, the twenty-first internal electrodes  328   c  are provided on the same dielectric layer  26  at the predetermined interval  332   d  with the adjacent twenty-first internal electrode  328   c  in the direction connecting the first external electrode  34   a  and the second external electrode  34   b.    
     The at least two twenty-second internal electrodes  328   d  are provided on the same dielectric layer  26  at the predetermined interval  332   d  with the adjacent twenty-second internal electrode  328   d  in the direction connecting the first external electrode  34   a  and the second external electrode  34   b.    
     The twenty-first internal electrode  328   c  is opposed to a portion of the twenty-second internal electrode  328   d  and a portion of another twenty-second internal electrode  328   d . The twenty-second internal electrode  328   d  is opposed to any two of a portion of the nineteenth internal electrode  328   a , a portion of the twentieth internal electrode  328   b , a portion of the twenty-first internal electrode  328   c , and a portion of another twenty-first internal electrodes  328   c.    
     The case in which the first multilayer ceramic electronic component body  312  includes four capacitors that are connected in series in the first laminated body  24  will be described below as an example. 
     A nineteenth extended electrode portion  330   a  led out to the first end surface  24   e  of the first laminated body  24  is provided on one end side of the nineteenth internal electrode  328   a . A twentieth extended electrode portion  330   b  led out to the second end surface  24   f  of the first laminated body  24  is provided on one end side of the twentieth internal electrode  328   b . Specifically, the nineteenth extended electrode portion  330   a  on one end side of the nineteenth internal electrode  328   a  is exposed on the first end surface  24   e  of the first laminated body  24 , and connected to the first external electrode  34   a . The twentieth extended electrode portion  330   b  on one end side of the twentieth internal electrode  328   b  is exposed on the second end surface  24   f  of the first laminated body  24 , and connected to the second external electrode  34   b.    
     The twenty-first internal electrode  328   c  and the twenty-second internal electrode  328   d  do not include an extended electrode portion, and are not exposed on the surface of the first laminated body  24 . Thus, the twenty-first internal electrode  328   c  and the twenty-second internal electrode  328   d  are connected to neither the first external electrode  34   a  nor the second external electrode  34   b.    
     The twenty-second internal electrode  328   d  close to the first end surface  24   e  is opposed to a portion of the nineteenth internal electrode  328   a  and a portion of the twenty-first internal electrode  328   c . The twenty-second internal electrode  328   d  close to the second end surface  24   f  is opposed to a portion of the twentieth internal electrode  328   b  and a portion of the twenty-first internal electrode  328   c . The twenty-first internal electrode  328   c  is opposed to a portion of the twenty-second internal electrode  328   d  and a portion of another twenty-second internal electrodes  328   d . That is, the first laminated body  24  includes opposed electrode portions  332   a  in a portion in which a portion of the nineteenth internal electrode  328   a  is opposed to a portion of the twenty-second internal electrode  328   d  with the dielectric layer  26  interposed therebetween, a portion in which a portion of the twenty-second internal electrode  328   d  is opposed to a portion of the twenty-first internal electrode  328   c  with the dielectric layer  26  interposed therebetween, a portion in which a portion of another twenty-second internal electrode  328   d  is opposed to the portion of the twenty-first internal electrode  328   c  with the dielectric layer  26  interposed therebetween, and a portion in which a portion of the twentieth internal electrode  328   b  is opposed to a portion of the another twenty-second internal electrode  328   d  with the dielectric layer  26  interposed therebetween. In the case in which the first multilayer ceramic electronic component body  312  is a capacitor, the electrostatic capacitance is produced in each of the four opposed electrode portions  332   a.    
     The first laminated body  24  includes W gaps  332   b  between one end in the width direction y of the opposed electrode portion  332   a  and the first side surface  24   c  and between the other end in the width direction y of the opposed electrode portion  332   a  and the second side surface  24   d . The first laminated body  24  includes the intervals  332   d  between the leading end of the nineteenth internal electrode  328   a  and one end of the twenty-first internal electrode  328   c , between the leading end of the twentieth internal electrode  328   b  and the other end of the twenty-first internal electrode  328   c , and between one end of the twenty-second internal electrode  328   d  and one end of another twenty-second internal electrode  328   d . The first laminated body  24  includes L gaps  332   c  between the other end of the twenty-second internal electrode  328   d  and the first end surface  24   e  and between the other end of the twenty-second internal electrode  328   d  and the second end surface  24   f.    
     In the first laminated body  24 , the internal electrode  328  may be disposed so as to be parallel or substantially parallel to the sheet-shaped insulator  22  (opposed to the insulator  22 ), or the internal electrode  328  may be disposed so as to be orthogonal or substantially orthogonal to the insulator  22 . 
     In the case in which the first multilayer ceramic electronic component body  312  is a capacitor, in the first laminated body  24 , in each opposed electrode portion  332   a , the nineteenth internal electrode  328   a  and the twenty-second internal electrode  328   d  are opposed to each other with the dielectric layer  26  interposed therebetween, the twenty-second internal electrode  328   d  and the twenty-first internal electrode  328   c  are opposed to each other with the dielectric layer  26  interposed therebetween, the twentieth internal electrode  328   b  and another twenty-second twelve internal electrodes  328   d  are opposed to each other with the dielectric layer  26  interposed therebetween, and the another twenty-second internal electrode  328   d  and the twentieth internal electrode  328   b  are opposed to each other with the dielectric layer interposed therebetween, thus producing the electrostatic capacitance. Consequently, in the first multilayer ceramic electronic component body  312 , the four capacitors are connected in series between the first external electrode  34   a  and the second external electrode  34   b . For this reason, the voltage applied to each capacitor is decreased, so that the internal withstand voltage is able to be further increased. 
     The second multilayer ceramic electronic component body  14  has the same or substantially the same configuration as the first multilayer ceramic electronic component body  12 , and the same or similar portions as those of the first multilayer ceramic electronic component body  12  are denoted by the same reference numerals, and the detailed description thereof is omitted. 
     As illustrated in  FIGS. 5 to 8 , the second laminated body  44  includes a plurality of laminated dielectric layers  46  and a plurality of laminated internal electrodes  48 . The second laminated body  44  includes a third main surface  44   a  and a fourth main surface  44   b , which are opposed to each other in the lamination direction x, a third side surface  44   c  and a fourth side surface  44   d , which are opposite to each other in the width direction y orthogonal or substantially orthogonal to the lamination direction x, and a third end surface  44   e  and a fourth end surface  44   f , which are opposed to each other in the length direction z orthogonal or substantially orthogonal to the lamination direction x and the width direction y. 
     The second laminated body  44  includes an outer layer  46   a  including a plurality of dielectric layers  46 , and an inner layer  46   b  including one or more of dielectric layers  46  and a plurality of internal electrodes  48  disposed on one or more of the dielectric layers  46 .

A region sandwiched between both of the outer layers  46   a  is the inner layer  46   b . In other words, the inner layer  46   b  includes the internal electrode  48 , and the outer layer  46   a  does not include the internal electrode  48 . 
     As illustrated in  FIG. 6 , the second laminated body  44  includes a plurality of rectangular or substantially rectangular third internal electrodes  48   a  and a plurality of rectangular or substantially rectangular fourth internal electrodes  48   b . The plurality of third internal electrodes  48   a  and the plurality of fourth internal electrodes  48   b  are buried so as to be alternately arranged at equal intervals along the lamination direction x of the second laminated body  44 . 
     A third extended electrode portion  50   a  led out to the third end surface  44   e  of the second laminated body  44  is provided on one end side of the third internal electrode  48   a . A fourth extended electrode portion  50   b  led out to the fourth end surface  44   f  of the second laminated body  44  is provided on one end side of the fourth internal electrode  48   b . Specifically, the third extended electrode portion  50   a  on one end side of the third internal electrode  48   a  is exposed on the third end surface  44   e  of the second laminated body  44 . The fourth extended electrode portion  50   b  on one end side of the fourth internal electrode  48   b  is exposed on the fourth end surface  44   f  of the second laminated body  44 .

In the case in which the second multilayer ceramic electronic component body  14  is a capacitor, the electrostatic capacitance is produced in the opposed electrode portion  52   a.    
     The second laminated body  44  includes side portions (hereinafter, referred to as “W gaps”)  52   b  of the second laminated body  44 , and the W gaps  52   b  between one end in the width direction y of the opposed electrode portion  52   a  and the third side surface  44   c  and between the other end in the width direction y of the opposed electrode portion  52   a  and the fourth side surface  44   d . The second laminated body  44  includes ends (hereinafter, referred to as “L gaps”)  52   c  of the second laminated body  44 , and the L gaps  52   c  are between an end of the third internal electrode  48   a  on the side opposite to the third extended electrode portion  50   a  and the fourth end surface  44   f  and between an end of the fourth internal electrode  48   b  on the side opposite to the fourth extended electrode portion  50   b  and the third end surface  44   e.    
     In the second laminated body  44 , the internal electrode  48  may be disposed so as to be parallel or substantially parallel to the sheet-shaped insulator  22  (opposed to the insulator  22 ), or the internal electrode  48  may be disposed so as to be orthogonal or substantially orthogonal to the insulator  22 . In the first preferred embodiment, the internal electrode  48  is preferably disposed so as to be parallel or substantially parallel to the insulator  22 . 
     The third external electrode  54   a  is disposed on the side of the third end surface  44   e  of the second laminated body  44 , and the fourth external electrode  54   b  is disposed on the side of the fourth end surface  44   f.    
     The third external electrode  54   a  is disposed on the surface of the third end surface  44   e  of the second laminated body  44 , extends from the third end surface  44   e , and covers a portion of each of the third main surface  44   a , the fourth main surface  44   b , the third side surface  44   c , and the fourth side surface  44   d . In this case, the third external electrode  54   a  is electrically connected to the third extended electrode portion  50   a  of the third internal electrode  48   a . Alternatively, the third external electrode  54   a  may be disposed only on the surface of the third end surface  44   e  of the second laminated body  44 .

Alternatively, the fourth external electrode  54   b  may be disposed only on the surface of the fourth end surface  44   f  of the second laminated body  44 . 
     In the case in which the second multilayer ceramic electronic component body  14  is a capacitor, in the second laminated body  44 , the third internal electrode  48   a  and the fourth internal electrode  48   b  are opposed to each other with the dielectric layer  46  interposed therebetween in each opposed electrode portions  52   a , thus producing the electrostatic capacitance. For this reason, the electrostatic capacitance is able to be obtained between the third external electrode  54   a  to which the third internal electrode  48   a  is connected and the fourth external electrode  54   b  to which the fourth internal electrode  48   b  is connected.

Alternatively, the third underlying electrode layer  58   a  may be disposed only on the surface of the third end surface  44   e  of the second laminated body  44 . 
     The fourth underlying electrode layer  58   b  is disposed on the surface of the fourth end surface  44   f  of the second laminate  44 , extends from the fourth end surface  44   f , and covers a portion of each of a third main surface  44   a , the fourth main surface  44   b , the third side surface  44   c , and the fourth side surface  44   d .

     A second multilayer ceramic electronic component body  114  in  FIGS. 9 to 13  is provided as another example of the second multilayer ceramic electronic component body  14  in  FIG. 1 . The structure of the second multilayer ceramic electronic component body  114  is the same as or similar to that of the second multilayer ceramic electronic component body  14  except for the internal electrode. Thus, the same or similar portions as those of the second laminated ceramic electronic component body  14  are denoted by the same reference numerals, and the description thereof is omitted. 
     The second multilayer ceramic electronic component body  114  includes two capacitors that are connected in series in the second laminated body  44 . 
     As illustrated in  FIG. 10 , the second laminated body  44  of the second multilayer ceramic electronic component body  114  includes an eighth internal electrode  148   a  connected to the third external electrode  54   a , a ninth internal electrode  148   b  on the same dielectric layer  46  as the eighth internal electrode  148   a  and connected to the fourth external electrode  54   b  while being spaced away from the eighth internal electrode  148   a  by a predetermined interval  152   d , and a tenth internal electrode  148   c  on a dielectric layer  46  different from the dielectric layer  46  on which the eighth internal electrode  148   a  and the ninth internal electrode  148   b  are located. The eighth internal electrode  148   a , the ninth internal electrode  148   b , and the tenth internal electrode  148   c  are buried so as to be alternately arranged at equal intervals along the lamination direction x of the second laminated body  44 . 
     An eighth extended electrode portion  150   a  led out to the third end surface  44   e  of the second laminated body  44  is provided on one end side of the eighth internal electrode  148   a . A ninth extended electrode portion  150   b  led out to the fourth end surface  44   f  of the second laminated body  44  is provided on one end side of the ninth internal electrode  148   b . Specifically, the eighth extended electrode portion  150   a  on one end side of the eighth internal electrode  148   a  is exposed on the third end surface  44   e  of the second laminated body  44 , and connected to the third external electrode  54   a . The ninth extended electrode portion  150   b  on one end side of the ninth internal electrode  148   b  is exposed on the fourth end surface  44   f  of the second laminated body  44 , and connected to the fourth external electrode  54   b.    
     The tenth internal electrode  148   c  does not include an extended electrode portion, and is not exposed on the surface of the second laminated body  44 . Thus, the tenth internal electrode  148   c  is connected to neither the third external electrode  54   a  nor the fourth external electrode  54   b.    
     The tenth internal electrode  148   c  is opposed to a portion of the eighth internal electrode  148   a  and a portion of the ninth internal electrode  148   b . That is, in the second laminated body  44 , opposed electrode portions  152   a  are provided in a portion in which a portion of the eighth internal electrode  148   a  is opposed to the tenth internal electrode  148   c  with the dielectric layer  46  interposed therebetween and a portion in which a portion of the ninth internal electrode  148   b  is opposed to the tenth internal electrode  148   c  with the dielectric layer  46  interposed therebetween. In the case in which the second multilayer ceramic electronic component body  114  is a capacitor, the electrostatic capacitance is produced in each of the two opposed electrode portions  152   a.    
     The second laminated body  44  includes W gaps  152   b  between one end in the width direction y of the opposed electrode portion  152   a  and the third side surface  44   c  and between the other end in the width direction y of the opposed electrode portion  152   a  and the fourth side surface  44   d . The second laminated body  44  includes L gaps  152   c  between one end of the tenth internal electrode  148   c  and the third end surface  44   e  and between the other end of the tenth internal electrode  148   c  and the fourth end surface  44   f.    
     In the second laminated body  44 , the internal electrode  148  may be disposed so as to be parallel or substantially parallel to the sheet-shaped insulator  22  (opposed to the insulator  22 ), or the internal electrode  148  may be disposed so as to be orthogonal or substantially orthogonal to the insulator  22 . 
     In the case in which the second multilayer ceramic electronic component body  114  is a capacitor, in the second laminated body  44 , in each opposed electrode portion  152   a , the eighth internal electrode  148   a  and the tenth internal electrode  148   c  are opposed to each other with the dielectric layer  46  interposed therebetween, and the ninth internal electrode  148   b  and the tenth internal electrode  148   c  are opposed to each other with the dielectric layer  46  interposed therebetween, thus producing the electrostatic capacitance. Consequently, in the second multilayer ceramic electronic component body  114 , the two capacitors are connected in series between the third external electrode  54   a  and the fourth external electrode  54   b . For this reason, the voltage applied to each capacitor is decreased, so that the internal withstand voltage is able to be further increased. 
     A second multilayer ceramic electronic component body  214  in  FIGS. 14 to 18  is provided as still another example of the second multilayer ceramic electronic component body  14  in  FIG. 1 . The structure of the second multilayer ceramic electronic component body  214  is the same as or similar to that of the second multilayer ceramic electronic component body  14  except for the internal electrode. Thus, the same or similar portions as those of the second laminated ceramic electronic component body  14  are denoted by the same reference numerals, and the description thereof is omitted. 
     The second multilayer ceramic electronic component body  214  includes at least three and odd-numbered capacitors that are connected in series in the second laminated body  44 . 
     As illustrated in  FIG. 15 , the second laminated body  44  of the second multilayer ceramic electronic component body  214  includes a fifteenth internal electrode  248   a  connected to the third external electrode  54   a , a sixteenth internal electrode  248   b , which is connected to the fourth external electrode  54   b  on a dielectric layer  46  different from the dielectric layer  46  on which the fifteenth internal electrode  248   a , at least one seventeenth internal electrode  248   c  on the same dielectric layer  46  as the fifteenth internal electrode  248   a  and spaced away from the fifteenth internal electrode  248   a  by a predetermined interval  252   d , and at least one eighteenth internal electrode  248   d  on the same dielectric layer  46  as the sixteenth internal electrode  248   b  and spaced away from the sixteenth internal electrode  248   b  by the predetermined interval  252   d.    
     In the case in which at least two seventeenth internal electrodes  248   c  are provided, the seventeenth internal electrodes  248   c  are provided on the same dielectric layer  46  at the predetermined interval  252   d  with the adjacent seventeenth internal electrode  248   c  in the direction connecting the third external electrode  54   a  and the fourth external electrode  54   b.    
     Similarly, in the case in which at least two eighteenth internal electrodes  248   d  are provided, the eighteenth internal electrodes  248   d  are provided on the same dielectric layer  46  at the predetermined interval  252   d  with the adjacent eighteenth internal electrode  248   d  in the direction connecting the third external electrode  54   a  and the fourth external electrode  54   b.    
     The seventeenth internal electrode  248   c  is opposed to any two of a portion of the sixteenth internal electrode  248   b , a portion of the eighteenth internal electrode  248   d , and a portion of another eighteenth internal electrode  248   d , and the eighteenth internal electrode  248   d  is opposed to any two of a portion of the fifteenth internal electrode  248   a , a portion of the seventeenth internal electrode  248   c , and a portion of another seventeenth internal electrode  248   c.    
     The case in which the second multilayer ceramic electronic component body  214  includes three capacitors that are connected in series in the second laminated body  44  will be described below as an example. 
     A fifteenth extended electrode portion  250   a  led out to the third end surface  44   e  of the second laminated body  44  is provided on one end side of the fifteenth internal electrode  248   a . A sixteenth extended electrode portion  250   b  led out to the fourth end surface  44   f  of the second laminated body  44  is provided on one end side of the sixteenth internal electrode  248   b . Specifically, the fifteenth extended electrode portion  250   a  on one end side of the fifteenth internal electrode  248   a  is exposed on the third end surface  44   e  of the second laminated body  44 , and connected to the third external electrode  54   a . The sixteenth extended electrode portion  250   b  on one end side of the sixteenth internal electrode  248   b  is exposed on the fourth end surface  44   f  of the second laminated body  44 , and connected to the fourth external electrode  54   b.    
     The seventeenth internal electrode  248   c  and the eighteenth internal electrode  248   d  do not include the extended electrode portion, and are not exposed on the surface of the second laminated body  44 . Thus, the seventeenth internal electrode  248   c  and the eighteenth internal electrode  248   d  are connected to neither the third external electrode  54   a  nor the fourth external electrode  54   b.    
     The seventeenth internal electrode  248   c  is opposed to a portion of the sixteenth internal electrode  248   b  and a portion of the eighteenth internal electrode  248   d . The eighteenth internal electrode  248   d  is opposed to a portion of the fifteenth internal electrode  248   a  and a portion of the seventeenth internal electrode  248   c . That is, the second laminated body  44  includes opposed electrode portions  252   a , which are provided in a portion in which a portion of the fifteenth internal electrode  248   a  is opposed to the eighteenth internal electrode  248   d  with the dielectric layer  46  interposed therebetween, a portion in which a portion of the seventeenth internal electrode  248   c  is opposed to a portion of the eighteenth internal electrode  248   d  with the dielectric layer  46  interposed therebetween, and a portion in which a portion of the sixteenth internal electrode  248   b  is opposed to the seventeenth internal electrode  248   c  with the dielectric layer  46  interposed therebetween. In the case in which the second multilayer ceramic electronic component body  214  is a capacitor, the electrostatic capacitance is produced in each of the three opposed electrode portions  252   a.    
     The second laminated body  44  includes W gaps  252   b  between one end in the width direction y of the opposed electrode portion  252   a  and the third side surface  44   c  and between the other end in the width direction y of the opposed electrode portion  252   a  and the fourth side surface  44   d . The second laminated body  44  includes the intervals  252   d  between the leading end of the fifteenth internal electrode  248   a  and one end of the seventeenth internal electrode  248   c  and between the leading end of the sixteenth internal electrode  248   b  and one end of the eighteenth internal electrode  248   d . The second laminated body  44  includes L gaps  252   c  between the other end of the seventeenth internal electrode  248   c  and the fourth end surface  44   f  and between the other end of the eighteenth internal electrode  248   d  and the third end surface  44   e.    
     In the second laminated body  44 , the internal electrode  248  may be disposed so as to be parallel or substantially parallel to the sheet-shaped insulator  22  (opposed to the insulator  22 ), or the internal electrode  248  may be disposed so as to be orthogonal or substantially orthogonal to the insulator  22 . 
     In the case in which the second multilayer ceramic electronic component body  214  is a capacitor, in the second laminated body  44 , in each opposed electrode portion  252   a , the fifteenth internal electrode  248   a  and the eighteenth internal electrode  248   d  are opposed to each other with the dielectric layer  46  interposed therebetween, the seventeenth internal electrode  248   c  and the eighteenth internal electrode  248   d  are opposed to each other with the dielectric layer  46  interposed therebetween, and the sixteenth internal electrode  248   b  and the seventeenth internal electrode  248   c  are opposed to each other with the dielectric layer  46  interposed therebetween thus producing the electrostatic capacitance. Consequently, in the second multilayer ceramic electronic component body  214 , the three capacitors are connected in series between the third external electrode  54   a  and the fourth external electrode  54   b . For this reason, the voltage applied to each capacitor is decreased, so that the internal withstand voltage is able to be further increased. 
     A second multilayer ceramic electronic component body  314  in  FIGS. 19 to 23  is provided as yet another example of the second multilayer ceramic electronic component body  14  in  FIG. 1 . The structure of the second multilayer ceramic electronic component body  314  is the same as or similar to that of the second multilayer ceramic electronic component body  14  except for the internal electrode. Thus, the same or similar portions as those of the second laminated ceramic electronic component body  14  are denoted by the same reference numerals, and the description thereof is omitted. 
     The second multilayer ceramic electronic component body  314  includes at least four and even-numbered capacitors that are connected in series in the second laminated body  44 . 
     As illustrated in  FIG. 20 , the second laminated body  44  of the second multilayer ceramic electronic component body  314  includes a twenty-third internal electrode  348   a  connected to the third external electrode  54   a , a twenty-fourth internal electrode  348  on the same dielectric layer  46  as the twenty-third internal electrode  348   a  and connected to the fourth external electrode  54   b , at least one twenty-fifth internal electrodes  348   c  on the same dielectric layer  46  as the twenty-third internal electrode  348   a  and the twenty-fourth internal electrode  348   b  and separated between the twenty-third internal electrode  348   a  and a twenty-fourth internal electrode  348   b  at a predetermined interval  352   d , and at least two twenty-sixth internal electrodes  348   d  on a dielectric layer  46  different from the dielectric layer  46  on which the twenty-third internal electrode  348   a  and the twenty-fourth internal electrode  348   b  are located. 
     In the case in which at least two twenty-fifth internal electrodes  348   c  are provided, the twenty-fifth internal electrodes  348   c  are provided on the same dielectric layer  46  at the predetermined interval  352   d  with the adjacent twenty-fifth internal electrode  348   c  in the direction connecting the third external electrode  54   a  and the fourth external electrode  54   b.    
     The at least two twenty-sixth internal electrodes  348   d  are provided on the same dielectric layer  46  at the predetermined interval  352   d  with the adjacent twenty-sixth internal electrode  348   d  in the direction connecting the third external electrode  54   a  and the fourth external electrode  54   b.    
     The twenty-fifth internal electrode  348   c  is opposed to a portion of the twenty-sixth internal electrode  348   d  and a portion of another twenty-sixth internal electrode  348   d . The twenty-sixth internal electrode  348   d  is opposed to any two of a portion of the twenty-third internal electrode  348   a , a portion of the twenty-fourth internal electrode  348   b , a portion of the twenty-fifth internal electrode  348   c , and a portion of another twenty-fifth twelfth internal electrode  348   c.    
     The case in which the second multilayer ceramic electronic component body  314  includes four capacitors that are connected in series in the second laminated body  44  will be described below as an example. 
     A twenty-third extended electrode portion  350   a  led out to the third end surface  44   e  of the second laminated body  44  is provided on one end side of the twenty-third internal electrode  348   a . A twenty-fourth extended electrode portion  350   b  led out to the fourth end surface  44   f  of the second laminated body  44  is provided on one end side of the twenty-fourth internal electrode  348   b . Specifically, the twenty-third extended electrode portion  350   a  on one end side of the twenty-third internal electrode  348   a  is exposed on the third end surface  44   e  of the second laminated body  44 , and connected to the third external electrode  54   a . The twenty-fourth extended electrode portion  350   b  on one end side of the twenty-fourth internal electrode  348   b  is exposed on the fourth end surface  44   f  of the second laminated body  44 , and connected to the fourth external electrode  54   b.    
     The twenty-fifth internal electrode  348   c  and the twenty sixth internal electrode  348   d  do not include the extended electrode portion, and are not exposed on the surface of the second laminated body  44 . Therefore, the twenty-fifth internal electrode  348   c  and the twenty-sixth internal electrode  348   d  are connected to neither the third external electrode  54   a  nor the fourth external electrode  54   b.    
     A twenty-sixth internal electrode  348   d  close to the third end surface  44   e  is opposed to a portion of the twenty-third internal electrode  348   a  and a portion of the twenty-fifth internal electrode  348   c . The twenty-sixth internal electrode  348   d  close to the fourth end surface  44   f  is opposed to a portion of the twenty-fourth internal electrode  348   b  and a portion of the twenty-fifth internal electrode  348   c . The twenty-fifth internal electrode  348   c  is opposed to a portion of the twenty-sixth internal electrode  348   d  and a portion of another twenty-sixth internal electrode  348   d . That is, the second laminated body  44  includes opposed electrode portions  352   a , which are provided in a portion in which a portion of the twenty-third internal electrode  348   a  is opposed to a portion of the twenty-sixth internal electrode  348   d  with the dielectric layer  46  interposed therebetween, a portion in which a portion of the twenty-third internal electrode  348   d  is opposed to a portion of the twenty-fifth internal electrode  348   c  with the dielectric layer  46  interposed therebetween, a portion in which a portion of another twenty-sixth internal electrode  348   d  is opposed to the portion of the twenty-fifth internal electrode  348   c  with the dielectric layer  46  interposed therebetween, and a portion in which a portion of the twenty-fourth internal electrode  348   b  is opposed to a portion of the another twenty-sixth internal electrode  348   d  with the dielectric layer  46  interposed therebetween. In the case in which the second multilayer ceramic electronic component body  314  is a capacitor, the electrostatic capacitance is produced in each of the four opposed electrode portions  352   a.    
     The second laminated body  44  includes W gaps  352   b  between one end in the width direction y of the opposed electrode portion  352   a  and the third side surface  44   c  and between the other end in the width direction y of the opposed electrode portion  352   a  and the fourth side surface  44   d . The second laminated body  44  includes the intervals  352   d  between the leading end of the twenty-third internal electrode  348   a  and one end of the twenty-fifth internal electrode  348   c , between the leading end of the twenty-fourth internal electrode  348   b  and the other end of the twenty-fifth internal electrode  348   c , and between one end of the twenty-sixth internal electrode  348   d  and one end of another twenty-sixth internal electrode  348   d . The second laminated body  44  includes L gaps  352   c  between the other end of the twenty-sixth internal electrode  348   d  and the third end surface  44   e  and between the other end of the twenty-sixth internal electrode  348   d  and the fourth end surface  44   f.    
     In the second laminated body  44 , the internal electrode  348  may be disposed so as to be parallel or substantially parallel to the sheet-shaped insulator  22  (opposed to the insulator  22 ), or the internal electrode  348  may be disposed so as to be orthogonal or substantially orthogonal to the insulator  22 . 
     In the case in which the second multilayer ceramic electronic component body  314  is a capacitor, in the second laminated body  44 , in each opposed electrode portion  352   a , the twenty-third internal electrode  348   a  and the twenty-sixth internal electrode  348   d  are opposed to each other with the dielectric layer  46  interposed therebetween, the twenty-sixth internal electrode  348   d  and the twenty-fifth internal electrode  348   c  are opposed to each other with the dielectric layer  46  interposed therebetween, the twenty-fifth internal electrode  348   c  and another twenty-sixth internal electrode  348   d  are opposed to each other with the dielectric layer  46  interposed therebetween, and the another twenty-sixth internal electrode  348   d  and twenty-fourth internal electrode  348   b  are opposed to each other with the dielectric layer  46  interposed therebetween, thus producing the electrostatic capacitance. Consequently, in the second multilayer ceramic electronic component body  314 , the four capacitors are connected in series between the third external electrode  54   a  and the fourth external electrode  54   b . For this reason, the voltage applied to each capacitor is decreased, so that the internal withstand voltage is able to be further increased. 
     As illustrated in  FIG. 1 , the first metal terminal  16  is connected to the second external electrode  34   b  of the first multilayer ceramic electronic component body  12  using a bonding material. The second metal terminal  18  is connected to the fourth external electrode  54   b  of the second multilayer ceramic electronic component body  14  using a bonding material. The first metal terminal  16  and the second metal terminal  18  are provided to mount the multilayer ceramic electronic component  10 A on the mounting substrate S. 
     The connection terminal  20  is connected across the first external electrode  34   a  of the first multilayer ceramic electronic component body  12  and the third external electrode  54   a  of the second multilayer ceramic electronic component body  14  using a bonding material. The connection terminal  20  is provided to connect the first multilayer ceramic electronic component body  12  and the second multilayer ceramic electronic component body  14  in series. Consequently, the first laminated body  24  and the second laminated body  44  are mounted on the mounting substrate S and connected in series, so that the withstand voltage of the multilayer ceramic electronic component  10 A is able to be improved. 
     The first metal terminal  16  includes a first terminal bonding portion  62  connected to the second external electrode  34   b  of the first multilayer ceramic electronic component body  12 , a first extended portion  64  that extends from the first terminal bonding portion  62  in the direction of the mounting surface such that a gap is provided between the multilayer ceramic electronic component body  12  and the mounting surface of the mounting substrate S, and a first mounting portion  66  that is connected to the first extended portion  64  and extends onto the side of the first multilayer ceramic electronic component body  12  in the direction connecting the second external electrode  34   b  and the fourth external electrode  54   b  (that is, extends in parallel or substantially in parallel to the mounting surface of the mounting substrate S from the first extended portion  64 ). 
     The second metal terminal  18  includes a second terminal bonding portion  82  connected to the fourth external electrode  54   b  of the second multilayer ceramic electronic component body  14 , a second extended portion  84  extending from the second terminal bonding portion  82  in the direction of the mounting surface such that a gap is provided between the multilayer ceramic electronic component body  14  and the mounting surface of the mounting substrate S, and a second mounting portion  86  that is connected to the second extended portion  84  and extends onto the side of the second multilayer ceramic electronic component body  14  in the direction connecting the second external electrode  34   b  and the fourth external electrode  54   b  (that is, extends from the second extended portion  84  in parallel or substantially in parallel to the mounting surface of the mounting substrate S). 
     The connection terminal  20  includes a third terminal bonding portion  92  connected to the first external electrode  34   a  of the first multilayer ceramic electronic component body  12 , a fourth terminal bonding portion  94  connected to the third external electrode  54   a  of the second multilayer ceramic electronic component body  14 , and a third extended portion  96  connected to the third terminal bonding portion  92  and the fourth terminal bonding portion  94  and located between the first external electrode  34   a  and the third external electrode  54   a  to extend in the direction connecting the first external electrode  34   a  and the third external electrode  54   a . The connection terminal  20  is in contact with the first end surface  22   e  (upper end surface, to be described later) of the insulator  22  by the third extended portion  96 . 
     The first terminal bonding portion  62  of the first metal terminal  16  is connected to the second external electrode  34   b  disposed on the second end surface  24   f  of the first laminated body  24 . The first terminal bonding portion  62  preferably has a plate shape, and one main surface opposed to the second end surface  24   f  of the first laminated body  24  is connected to the second external electrode  34   b  using a bonding material (not illustrated). The shape of the first terminal bonding portion  62  is not particularly limited, but preferably the first terminal bonding portion  62  has a rectangular or substantially rectangular shape, for example. 
     The second terminal bonding portion  82  of the second metal terminal  18  is connected to the fourth external electrode  54   b  disposed on the fourth end surface  44   f  of the second laminated body  44 . The second terminal bonding portion  82  preferably has a plate shape, and one main surface opposed to the fourth end surface  44   f  of the second laminated body  44  is connected to the fourth external electrode  54   b  using a bonding material (not illustrated). The shape of the second terminal bonding portion  82  is not particularly limited, but preferably the second terminal bonding portion  82  has a rectangular or substantially rectangular shape, for example. 
     The third terminal bonding portion  92  of the connection terminal  20  is connected to the first external electrode  34   a  disposed on the first end surface  24   e  of the first laminated body  24 . The third terminal bonding portion  92  preferably has a plate shape, and one main surface opposed to the first end surface  24   e  of the first laminated body  24  is connected to the first external electrode  34   a  using a bonding material (not illustrated). The shape of the third terminal bonding portion  92  is not particularly limited, but preferably the third terminal bonding portion  92  has a rectangular or substantially rectangular shape, for example. 
     The fourth terminal bonding portion  94  of the connecting terminal  20  is connected to the third external electrode  54   a  disposed on the third end surface  44   e  of the second laminated body  44 . The fourth terminal bonding portion  94  preferably has a plate shape, and one main surface opposed to the third end surface  44   e  of the second laminated body  44  is connected to the third external electrode  54   a  using a bonding material (not illustrated). The shape of the fourth terminal bonding portion  94  is not particularly limited, but preferably the fourth terminal bonding portion  94  has a rectangular or substantially rectangular shape, for example. 
     The first extended portion  64  of the first metal terminal  16  is connected to the first terminal bonding portion  62 , extends in the direction of the mounting surface such that a gap is provided between the second end surface  24   f  of the first laminated body  24  and the mounting surface of the mounting substrate S, and is connected to the first mounting portion  66 . A length of the first extended portion  64  is designed such that a gap is provided between the second end surface (lower end surface)  22   f  of the insulator  22  protruding from the first multilayer ceramic electronic component body  12  toward the mounting surface side of the mounting substrate S and the mounting surface of the mounting substrate S. 
     The first extended portion  64  extends in a direction parallel or substantially parallel to the first main surface  24   a  or the second main surface  24   b  of the first laminated body  24 . In other words, the first extended portion  64  intersects the first terminal bonding portion  62  and the first mounting portion  66  at right angles. However, the first extended portion  64  may be inclined with respect to the first main surface  24   a  or the second main surface  24   b  of the first laminated body  24 . The shape of the first extended portion  64  is not particularly limited, but preferably the first extended portion  64  has a rectangular or substantially rectangular shape, for example. 
     The second extended portion  84  of the second metal terminal  18  is connected to the second terminal bonding portion  82 , extends in the direction of the mounting surface such that a gap is provided between the fourth end surface  44   f  of the second laminated body  44  and the mounting surface of the mounting substrate S, and is connected to the second mounting portion  86 . A length of the second extended portion  84  is designed such that a gap is provided between the second end surface (lower end surface)  22   f  of the insulator  22  protruding from the second multilayer ceramic electronic component body  14  toward the mounting surface side of the mounting substrate S and the mounting surface of the mounting substrate S. 
     The second extended portion  84  extends in a direction parallel or substantially parallel to the third main surface  44   a  or the fourth main surface  44   b  of the second laminated body  44 . In other words, the second extended portion  84  intersects the second terminal bonding portion  82  and the second mounting portion  86  at right angles. However, the second extended portion  84  may be inclined with respect to the third main surface  44   a  or the fourth main surface  44   b  of the second laminated body  44 . The shape of the second extended portion  84  is not particularly limited, but preferably the second extended portion  84  has a rectangular or substantially rectangular shape, for example. 
     The first extended portion  64  of the first metal terminal  16  and the second extended portion  84  of the second metal terminal  18  are provided to space the first multilayer ceramic electronic component body  12  and the second multilayer ceramic electronic component body  14  away from the mounting substrate S on which the multilayer ceramic electronic component  10 A is mounted. Consequently, a stress caused by a difference in thermal expansion coefficient between the mounting substrate S and the multilayer ceramic electronic component  10 A, a stress caused by deflection of the mounting substrate S, or a mechanical distortion generated in the dielectric layer due to application of voltage is absorbed by elastic deformation of the first extended portion  64  and the second extended portion  84 . As a result, problems, such as a crack being generated in the first multilayer ceramic electronic component body  12  and the second multilayer ceramic electronic component body  14  and the second external electrode  34   b  being peeled off from the first multilayer ceramic electronic component body  12  are prevented, and the generation of a noise (squeal) is reduced by reducing or preventing transmission of vibration to the mounting substrate S through the first metal terminal  16  and the second metal terminal  18 . 
     The third extended portion  96  of the connection terminal  20  is connected to the third terminal bonding portion  92  and the fourth terminal bonding portion  94 , and extends such that a gap is provided between the first multilayer ceramic electronic component body  12  and the second multilayer ceramic electronic component body  14 . The third extended portion  96  is in close contact with the insulator  22 . The shape of the third extended portion  96  is not particularly limited, but preferably the third extended portion  96  has a rectangular or substantially rectangular shape, for example. 
     The first mounting portion  66  of the first metal terminal  16  is connected to the first extended portion  64 , and mounted on the mounting substrate S. Specifically, the first mounting portion  66  is bent from a terminal end of the first extended portion  64 , and extends so as to be parallel or substantially parallel to the mounting surface. The shape of the first mounting portion  66  is not particularly limited, but preferably the first mounting portion  66  has a rectangular or substantially rectangular shape, for example. 
     The second mounting portion  86  of the second metal terminal  18  is connected to the second extended portion  84 , and mounted on the mounting substrate S. Specifically, the second mounting portion  86  is bent from the terminal end of the second extended portion  84 , and extends so as to be parallel or substantially parallel to the mounting surface. The shape of the second mounting portion  86  is not particularly limited, but preferably the second mounting portion  86  has a rectangular or substantially rectangular shape, for example. 
     The mounting surfaces of the first mounting portion  66  and the second mounting portion  86  are flat or substantially flat with respect to the mounting surface of the mounting substrate S, so that the multilayer ceramic electronic component  10 A is able to be sucked by a mounter (automatic mounting machine). 
     In the first preferred embodiment, the first metal terminal  16 , the second metal terminal  18 , and the connection terminal  20  are preferably plate-shaped frame terminals, for example. Consequently, bonding using the solder or the conductive adhesive is ensured, and surface mounting is able to be performed. However, the connection terminal  20  may be a lead terminal. 
     The first metal terminal  16  and the second metal terminal  18  preferably have a substantially U-shaped in cross section, for example. Thus, between the second external electrode  34   b  and the first metal terminal  16 , between the fourth external electrode  54   b  and the second metal terminal  18 , and between the mounting substrate S and the first metal terminal  16  and the second metal terminal  18 , a bonding area is increased, a contact resistance is decreased, and the physical bonding is ensured. As a result, resistance to the deflection of the mounting substrate S is able to be improved when the multilayer ceramic electronic component  10 A is mounted on the mounting substrate S. The shapes of the first metal terminal  16  and the second metal terminal  18  are not limited as long as the resistance to the deflection of the mounting substrate S is able to be improved. 
     The first metal terminal  16 , the second metal terminal  18 , and the connection terminal  20  include a terminal body and a plating film provided on the surface of the terminal body. 
     Preferably the terminal body is made of, for example Ni, Fe, Cu, Ag, Cr, or an alloy mainly including at least one of these metals. Specifically, for example, the metal of the base material of the terminal body may preferably be Fe-42 Ni alloy, Fe-18 Cr alloy, or Cu-8 Sn alloy. Preferably, the thicknesses of the first metal terminal  16 , the second metal terminal  18 , and the connection terminal  20  are in a range of about 0.05 mm to about 0.5 mm, for example. 
     For example, the plating film includes a lower plating film and an upper plating film. 
     The lower plating film is provided on the surface of the terminal body, and the upper plating film is provided on the surface of the lower plating film. Each of the lower plating film and the upper plating film may include a plurality of plating layers. 
     The plating film may not be provided in at least peripheral surfaces of the first extended portion  64  and the first mounting portion  66  of the first metal terminal  16  and peripheral surfaces of the second extended portion  84  and the second mounting portion  86  of the second metal terminal  18 . Consequently, spread of solder to the first metal terminal  16  and the second metal terminal  18  is able to be prevented when the multilayer ceramic electronic component  10 A is mounted on the mounting substrate S using the solder. The spread of the solder is prevented between the first multilayer ceramic electronic component body  12  and the first metal terminal  16  (floating portion) and between the second multilayer ceramic electronic component body  14  and the second metal terminal  18  (floating portion), so that the floating portion is prevented from being filled with the solder. Thus, a space of the floating portion is sufficiently ensured. The first extended portion  64  of the first metal terminal  16  and the second extended portion  84  of the second metal terminal  18  are easily elastically deformed, so that the mechanical distortion generated in the ceramic layer due to the application of the AC voltage is able to be further absorbed. This enables the vibration generated at this time to be prevented from being transmitted to the mounting substrate S through the second external electrode  34   b  and the fourth external electrode  54   b . Thus, the generation of an acoustic noise (squeal) is able to be reduced or prevented by including the first metal terminal  16  and the second metal terminal  18 . The plating film may not be provided on the entire peripheral surfaces of the first metal terminal  16  and the second metal terminal  18 . 
     A removal (cutting, polishing) method using a machine, a removal method by laser trimming, a removal method by a plating remover (for example, sodium hydroxide), and a method of covering a portion not to be plated with the resist film before forming the plating film on the first metal terminal  16  and the second metal terminal  18  and removing the resist film after forming the plating film on the first metal terminal  16  and the second metal terminal  18  are conceivable in the case in which the plating films of the first extended portion  64  and the first mounting portion  66  of the first metal terminal  16  and the second extended portion  84  and the second mounting portion  86  of the second metal terminal  18  or the entire peripheral surfaces of the first metal terminal  16  and the second metal terminal  18  are removed. 
     Preferably the lower plating film is made of, for example, Ni, Fe, Cu, Ag, Cr or an alloy mainly including at least one of these metals. More preferably, the lower plating film is made of, for example, Ni, Fe, Cr or an alloy mainly including at least one of these metals. Preferably, the thickness of the lower plating film is in a range of about 0.2 μm to about 5.0 μm, for example. 
     Preferably, the upper plating film is made of, for example, Sn, Ag, Au, or an alloy mainly including at least one of these metals. More preferably, the upper plating film is made of, for example, Sn or an alloy mainly including Sn. The upper plating film is preferably made of Sn or an alloy mainly including Sn, which improves solderability between the first metal terminal  16 , the second metal terminal  18  and the connection terminal  20  and the external electrode. Preferably, the thickness of the upper plating film is in a range of about 1.0 μm to about 5.0 μm, for example. 
     Each of the terminal body and the lower plating film is preferably made of, for example, Ni, Fe, Cr having a high melting point, or an alloy mainly including at least one of these metals, which improves heat resistance of the external electrode. 
     The bonding material is not particularly limited. For example, the solder or the conductive adhesive may be used. 
     Preferably, Sn—Sb base, Sn—Ag—Cu base, Sn—Cu base, or Sn—Bi base LF solder, for example, is used in the case in which solder is used. For the Sn—Sb base solder, preferably an Sb content is in a range of about 5% to 15%, for example. 
     Preferably, a bonding agent in which a metal filler made of Ag is added to a thermosetting resin, such as an epoxy resin, for example, is used in the case in which the conductive adhesive is used.

     The first metal terminal  116  preferably has an inverted or substantially inverted L-shaped in section, for example, and may be a frame terminal or a lead terminal. The first terminal bonding portion  162  of the first metal terminal  116  is connected to the second external electrode  34   b  disposed on the second end surface  24   f  of the first laminated body  24  using a bonding material.

     The first extended portion  164  of the first metal terminal  116  is connected to the first terminal bonding portion  162 , extends in the direction of the mounting surface such that a gap is provided between the second end surface  24   f  of the first laminated body  24  and the mounting surface of the mounting substrate S, and is connected to the first mounting portion  166 . The first extended portion  164  extends in a direction parallel or substantially parallel to the first main surface  24   a  or the second main surface  24   b  of the first laminated body  24 . In other words, the first extended portion  164  intersects the first terminal bonding portion  162  substantially at right angles. 
     The second extended portion  184  of the second metal terminal  118  is connected to the second terminal boding unit  182 , extends in the direction of the mounting surface such that a gap is provided between the fourth end surface  44   f  of the second laminated body  44  and the mounting surface of the mounting substrate S, and is connected to the second mounting portion  186 .

     The second mounting portion  186  of the second metal terminal  118  is connected to the second extended portion  184 , and mounted on the mounting substrate S. Specifically, the second mounting portion  186  extends on the extension line from the terminal end of the second extended portion  184 . 
     In the case in which the first metal terminal  116  and the second metal terminal  118  are a lead terminal, the first mounting portion  166  and the second mounting portion  186  are inserted into through holes of the mounting substrate S, and the multilayer ceramic electronic component  10 A is able to be inserted and mounted. The multilayer ceramic electronic component  10 A may also be mounted by welding the first metal terminal  116  and the second metal terminal  118 . 
     A first metal terminal  216  and a second metal terminal  218  in  FIG. 25  are provided as another example of the first metal terminal  16  and the second metal terminal  18  in  FIG. 1 .  FIG. 25  is a front view of a multilayer ceramic electronic component for illustrating another modification of the metal terminal in  FIG. 1 . 
     The first metal terminal  216  includes a first terminal bonding portion  262  connected to the second external electrode  34   b  of the first multilayer ceramic electronic component body  12 , a first extended portion  264  that extends on the extension line from the first terminal bonding portion  262  and extends in the direction of the mounting surface such that a gap is provided between the first multilayer ceramic electronic component body  12  and the mounting surface of the mounting substrate S, and a first mounting portion  266  that is connected to the first extended portion  264  and extends onto the side of the first multilayer ceramic electronic component body  12  in the direction connecting the second external electrode  34   b  and the fourth external electrode  54   b  (that is, extends from the first extended portion  264  in parallel or substantially in parallel to the mounting surface of the mounting substrate S). 
     The first metal terminal  216  preferably has an L-shape or a substantially L-shape in cross section, for example, and may be a frame terminal or a lead terminal. 
     The second metal terminal  218  includes a second terminal bonding portion  282  connected to the fourth external electrode  54   b  of the second multilayer ceramic electronic component body  14 , a second extended portion  284  extending on the extension line from the second terminal bonding portion  282  and extends in the direction of the mounting surface such that a gap is provided between the multilayer ceramic electronic component body  14  and the mounting surface of the mounting substrate S, and a second mounting portion  286  that is connected to the second extended portion  284  and extends onto the side of the second multilayer ceramic electronic component body  14  in the direction connecting the second external electrode  34   b  and the fourth external electrode  54   b  (that is, extends from the second extended portion  284  in parallel to the mounting surface of the mounting substrate S). 
     The second metal terminal  118  preferably has an L-shape or a substantially L-shape in section, for example, and may be a frame terminal or a lead terminal. 
     The first terminal bonding portion  262  of the first metal terminal  216  is connected to the second external electrode  34   b  located on the first main surface  24   a , the second main surface  24   b , the first side surface  24   c , or the second side surface  24   d  of the first laminated body  24  using a bonding material. That is, when any one of the first main surface  24   a , the second main surface  24   b , the first side surface  24   c , and the second side surface  24   d  of the first laminated body  24  of the first multilayer ceramic electronic component body  12  is in contact with the insulator  22 , the first terminal bonding portion  262  is connected to the second external electrode  34   b  located on a surface opposed to the contact surface using a bonding material. 
     For example, in the first preferred embodiment, because the first main surface  24   a  of the first laminated body  24  of the first multilayer ceramic electronic component body  12  is in contact with the insulator  22 , the first terminal bonding portion  262  is connected to the second external electrode  34   b  located on the second main surface  24   b  opposed to the first main surface  24   a  using a bonding material. 
     The second terminal bonding portion  282  of the second metal terminal  218  is connected to the fourth external electrode  54   b  located on the third main surface  44   a , the fourth main surface  44   b , the third side surface  44   c , or the fourth side surface  44   d  of the second laminated body  44  using a bonding material. That is, when any one of the third main surface  44   a , the fourth main surface  44   b , the third side surface  44   c , or the fourth side surface  44   d  of the second laminated body  44  of the second multilayer ceramic electronic component body  14  is in contact with the insulator  22 , the second terminal bonding portion  282  is connected to the fourth external electrode  54   b  located on a surface opposed to the contact surface using a bonding material. 
     For example, in the first preferred embodiment, because the fourth main surface  44   b  of the second laminated body  44  of the second multilayer ceramic electronic component body  14  is in contact with the insulator  22 , the second terminal bonding portion  282  is connected to the fourth external electrode  54   b  located on the third main surface  44   a  opposed to the fourth main surface  44   b  using a bonding material. 
     The first extended portion  264  of the first metal terminal  216  is connected to the first terminal bonding portion  262 , extends in the direction of the mounting surface such that a gap is provided between the second end surface  24   f  of the first laminated body  24  and the mounting surface of the mounting substrate S, and is connected to the first mounting portion  266 . The first extended portion  264  extends in a direction parallel or substantially parallel to the first main surface  24   a  or the second main surface  24   b  of the first laminated body  24 . In other words, the first extended portion  264  intersects the first mounting portion  266  substantially at right angles. 
     The second extended portion  284  of the second metal terminal  218  is connected to the second terminal bonding portion  282 , extends in the direction of the mounting surface such that a gap is provided between the fourth end surface  44   f  of the second laminated body  44  and the mounting surface of the mounting substrate S, and is connected to the second mounting portion  286 . The second extended portion  284  extends in a direction parallel or substantially parallel to the third main surface  44   a  or the fourth main surface  44   b  of the second laminated body  44 . In other words, the second extended portion  284  intersects the second mounting portion  286  substantially at right angles. 
     The first mounting portion  266  of the first metal terminal  216  is connected to the first extended portion  264 , and mounted on the mounting substrate S. Specifically, the first mounting portion  266  is bent from the terminal end of the first extended portion  264 , and extends so as to be parallel or substantially parallel to the mounting surface. 
     The second mounting portion  286  of the second metal terminal  218  is connected to the second extended portion  284 , and mounted on the mounting substrate S. Specifically, the second mounting portion  286  is bent from the terminal end of the second extended portion  284 , and extends so as to be parallel or substantially parallel to the mounting surface. 
     Because the first metal terminal  216  and the second metal terminal  218  preferably have the L-shape or substantially L-shape in section, the first terminal bonding portion  262  and the second terminal bonding portion  282  is small. Thus, a total length of the first metal terminal  216  and the second metal terminal  218  is shortened, and a cost is able to be reduced. 
     The height dimension of the multilayer ceramic electronic component  10  is easily adjusted only by changing the bonding position between the first terminal bonding portion  262  and the second external electrode  34   b  and the bonding position between the second terminal bonding portion  282  and the fourth external electrode  54   b.    
     As illustrated in  FIGS. 1 and 2 , the insulator  22  is disposed between the first multilayer ceramic electronic component body  12  and the second multilayer ceramic electronic component body  14 . The insulator  22  includes a first main surface  22   a  and a second main surface  22   b  that are opposed to each other in the thickness direction (the length direction L of the multilayer ceramic electronic component  10 A), a first side surface  22   c  and a second side surface  22   d  that are opposed to each other in the width direction W orthogonal or substantially orthogonal to the length direction L of the multilayer ceramic electronic component  10 A, and a first end surface (hereinafter, also referred to as upper end surface)  22   e  and a second end surface (hereinafter, also referred to as lower end surface)  22   f  that are opposed to each other in the height direction T orthogonal or substantially orthogonal to the length direction L and the width direction W of the multilayer ceramic electronic component  10 A. 
     The size of the insulator  22  is longer than the lengths of the first multilayer ceramic electronic component body  12  and the second multilayer ceramic electronic component body  14  in the height direction T, and is longer than the width dimensions of the first multilayer ceramic electronic component body  12  and the second multilayer ceramic electronic component body  14  in the width direction W. 
     The insulator  22  is disposed such that the first main surface  24   a  or the second main surface  24   b  of the first laminated body  24  of the first multilayer ceramic electronic component body  12  is in contact with the first main surface  22   a  of the insulator  22 , and such that the third main surface  44   a  or the fourth main surface  44   b  of the second laminated body  44  of the second multilayer ceramic electronic component body  14  is in contact with the second main surface  22   b  of the insulator  22 . Alternatively, the insulator  22  is disposed such that the first side surface  24   c  or the second side surface  24   d  of the first laminated body  24  of the first multilayer ceramic electronic component body  12  is in contact with the first main surface  22   a  of the insulator  22 , and such that the third side surface  44   c  or the fourth side surface  44   d  of the second laminated body  44  of the second multilayer ceramic electronic component body  14  is in contact with the second main surface  22   b  of the insulator  22 . 
     In the first preferred embodiment, the insulator  22  is disposed such that the first main surface  22   a  is in contact with the first main surface  24   a  of the first laminated body  24  of the first multilayer ceramic electronic component body  12 , and such that the second main surface  22   b  is in contact with the fourth main surface  44   b  of the second laminated body  44  of the second multilayer ceramic electronic component body  14 . 
     In the insulator  22 , the first end surface (upper end surface)  22   e  is in contact with the lower surface of the third extended portion  96  of the connection terminal  20 , and the second end surface (lower end surface)  22   f  protrudes from the second end surface  24   f  of the first multilayer ceramic electronic component body  12  and the fourth end surface  44   f  of the second multilayer ceramic electronic component body  14 . In the insulator  22 , the first side surface  22   c  protrudes from the first side surface  24   c  of the first multilayer ceramic electronic component body  12  and the third side surface  44   c  of the second multilayer ceramic electronic component body  14 , and the second side surface  22   d  protrudes from the second side surface  24   d  of the first multilayer ceramic electronic component body  12  and the fourth side surface  44   d  of the second multilayer ceramic electronic component body  14 . Thus, the insulator  22  protrudes from the second external electrode  34   b  of the first multilayer ceramic electronic component body  12  and the fourth external electrode  54   b  of the second multilayer ceramic electronic component body  14  in the lower portion in the height direction T, so that the insulator  22  effectively reduces or prevents edge-surface discharge between the second external electrode  34   b  and the fourth external electrode  54   b.    
     In this manner, by disposing the insulator  22  between the first multilayer ceramic electronic component body  12  and the second multilayer ceramic electronic component body  14 , the first multilayer ceramic electronic component body  12  and the second multilayer ceramic electronic component body  14  are insulated from each other, and connected in series. Consequently, the first metal terminal  16  and the second metal terminal  18  are insulated from each other, and the first laminated body  24  of the first multilayer ceramic electronic component body  12  and the second laminated body  44  of the second multilayer ceramic electronic component body  14  are connected in series, so that the advantageous effect of improving the withstand voltage of the multilayer ceramic electronic component  10 A is able to be obtained. 
     The first laminated body  24  and the second laminate  44  are in contact with the insulator  22 , and the advantageous effect of stabilizing the bonding relationship between the connection terminal  20  and the first laminated body  24  and the second laminate  44  is able to be obtained. 
     An insulating sheet or a resin, for example, may preferably be used as the insulator  22 . In the case in which the insulating sheet is used, the insulator  22  is thin, so that the dimensions of the multilayer ceramic electronic component  10 A are able to be reduced. For example, a ceramic sheet, a rubber sheet, or an epoxy film can be used as the insulating sheet. Preferably the thickness of the insulating sheet is in a range of about 0.2 mm to about 2 mm, for example. 
     In the case in which the resin is used as the insulator  22 , the withstand voltage of the insulator  22  is increased, and the multilayer ceramic electronic component  10 A having high withstand voltage is able to be provided. For example, an epoxy resin, a phenol resin, a polyurethane resin, a silicone resin, or a polyimide resin may preferably be used as the resin. 
     The insulator  22  may be provided such that the first end surface (upper end surface)  22   e  is spaced apart from the lower surface of the third extended portion  96  of the connection terminal  20 . Consequently, the size of the insulator  22  is able to be reduced so as to reduce the cost. 
     In the multilayer ceramic electronic component  10 A having the above-described structure, because the first multilayer ceramic electronic component body  12  and the second multilayer ceramic electronic component body  14  are connected in series, the voltage applied to each of the first multilayer ceramic electronic component body  12  and the second multilayer ceramic electronic component body  14  is decreased, and the high withstand voltage is able to be achieved. 
     As compared to the disposition of the conventional multilayer ceramic electronic components side by side on the mounting substrate, a mounting area is able to be reduced when the single multilayer ceramic electronic component  10 A according to a preferred embodiment of the present invention is disposed on the mounting substrate. In the monolithic ceramic electronic component  10 A, the acquired electrostatic capacitance is increased with respect to the mounting area as compared to the multilayer ceramic electronic component described in Patent Application Laid-Open No. 2003-272946 having the configuration in which the plurality of capacitors are connected in the ceramic laminated body. Thus, the acquired capacitance is secured and the reduction of the mounting area is able to be achieved in the multilayer ceramic electronic component  10 A. 
     Second Preferred Embodiment 
     A multilayer ceramic electronic component according to a second preferred embodiment of the present invention will be described.  FIG. 26  is a front view illustrating the multilayer ceramic electronic component of the second preferred embodiment of the present invention. A multilayer ceramic electronic component  10 B of the second preferred embodiment is similar to the multilayer ceramic electronic component  10 A of the first preferred embodiment in  FIG. 1  except for the insulator. Thus, the same or similar portions as those of the multilayer ceramic electronic component  10 A are denoted by the same reference numerals, and the description thereof is omitted. 
     As illustrated in  FIG. 26 , an insulator  400  (denoted by a two-dot chain line) is preferably a resin, for example, and the resin is disposed between the first multilayer ceramic electronic component body  12  and the second multilayer ceramic electronic component body  14 , and disposed so as to cover the first multilayer ceramic electronic component body  12 , the second multilayer ceramic electronic component body  14 , a portion (first terminal bonding portion  62 ) of the first metal terminal  16 , a portion (second terminal bonding portion  82 ) of the second metal terminal  18 , and the connection terminal  20  (hereinafter, referred to as exterior resin  400 ). 
     In the case in which the first metal terminal  16  and the second metal terminal  18  are a plate-shaped frame terminal, the bonding using the solder or the conductive adhesive is ensured, and surface mounting is able to be performed. 
     In the multilayer ceramic electronic component  10 B having the above-described configuration, the exterior resin  400  is only slightly larger than the width dimensions of the first multilayer ceramic electronic component body  12  and the second multilayer ceramic electronic component body  14 , so that the size of the multilayer ceramic electronic component  10 B is able to be reduced. 
     The edge-surface discharges of the second external electrode  34   b  and the fourth external electrode  54   b  are prevented by using the exterior resin  400 . The multilayer ceramic electronic component  10 B is covered with the resin, so that a gas (such as sulfur) corrosion resistance is improved. The bonding unit between the first metal terminal  16  and the second external electrode  34   b  and the bonding unit between the second metal terminal  18  and the fourth external electrode  54   b  are covered with the resin, so that physical bonding stability and the heat resistance of the bonding unit are improved. 
     As illustrated in  FIG. 27 , the first metal terminal  16  and the second metal terminal  18  are deformed such that the first extended portion  64  and the second extended portion  84  are exposed and extend from a side portion of the exterior resin  400 , so that a creeping distance between the first mounting portion  66  of the first metal terminal  16  and the second mounting portion  86  of the second metal terminal  18  is able to be lengthened to prevent the edge-surface discharge. 
     The first metal terminal  116  and the second metal terminal  118  in  FIG. 28  are provided as another example of the first metal terminal  16  and the second metal terminal  18  in  FIG. 26 . Because the first metal terminal  116  and the second metal terminal  118  is already described with reference to  FIG. 24 , the detailed description is omitted. 
     The exterior resin  400  is disposed between the first multilayer ceramic electronic component body  12  and the second multilayer ceramic electronic component body  14 , and disposed so as to cover the first multilayer ceramic electronic component body  12 , the second multilayer ceramic electronic component body  14 , a portion (first terminal bonding portion  162 ) of the first metal terminal  116 , a portion (second terminal bonding portion  182 ) of the second metal terminal  118 , and the connection terminal  20 . 
     In the case in which the first metal terminal  116  and the second metal terminal  118  are lead terminals, the first mounting portion  166  and the second mounting portion  186  are inserted into through holes of the mounting substrate S, and the multilayer ceramic electronic component  10 B is able to be inserted and mounted. 
     As illustrated in  FIG. 29 , the first metal terminal  116  and the second metal terminal  118  are deformed such that the first extended portion  164  and the second extended portion  184  are exposed and extend from the side portion of the exterior resin  400 , so that the creeping distance between the first metal terminal  116  and the second metal terminal  118  is able to be lengthened to prevent the edge-surface discharge.

A multilayer ceramic electronic component  10 C of the third preferred embodiment is similar to the multilayer ceramic electronic component  10 B of the second preferred embodiment in  FIG. 26  except for the metal terminal and the connection terminals. Therefore, the same or similar portions as those of the multilayer ceramic electronic component  10 B are denoted by the same reference numerals, and the description thereof is omitted. 
     As illustrated in  FIG. 30 , a first metal terminal  316  is connected to the first external electrode  34   a  of the first multilayer ceramic electronic component body  12  using a bonding material.

The fourth terminal bonding portion  394  preferably has a plate shape. 
     The first extended portion  364  of the first metal terminal  316  slightly extends outward from the first terminal bonding portion  362  on the extension line of the first terminal bonding portion  362  to be extended out to the side portion of the exterior resin  400  such that a gap is provided between the first extended portion  364  and the second main surface  24   b  of the first multilayer ceramic electronic component body  12 , namely, such that the first extended portion  364  does not contact the second external electrode  34   b  disposed on the second main surface  24   b  of the first laminated body  24 . The first extended portion  364  is bent at right angles on the surface of the insulator, extends along the side portion in the direction of the mounting surface such that a gap is provided between the first multilayer ceramic electronic component body  12  and the mounting surface of the mounting substrate S, and is connected to the first mounting portion  366 . 
     The first extended portion  364  extends in a direction parallel or substantially parallel to the first main surface  24   a  or the second main surface  24   b  of the first laminated body  24 . In other words, the first extended portion  364  intersects the first terminal bonding portion  362  and the first mounting portion  366  substantially at right angles. However, the first extended portion  364  may be inclined with respect to the first main surface  24   a  or the second main surface  24   b  of the first laminated body  24 . 
     The second extended portion  384  of the second metal terminal  318  slightly extends outward from the first terminal bonding portion  382  on the extension line of the first terminal bonding portion  382  to be extended out to the side portion of the exterior resin  400  such that a gap is provided between the second extended portion  384  and the first main surface  44   a  of the second multilayer ceramic electronic component body  14 , namely, such that the second extended portion  384  does not contact the fourth external electrode  54   b  disposed on the first main surface  44   e  of the second laminated body  44 .

     The second extended portion  384  extends in a direction parallel or substantially parallel to the third main surface  44   a  or the fourth main surface  44   b  of the second laminated body  44 . In other words, the second extended portion  384  intersects the second terminal bonding portion  382  and the second mounting portion  386  substantially at right angles. However, the second extended portion  384  may be inclined with respect to the third main surface  44   a  or the fourth main surface  44   b  of the second laminated body  44 . 
     The first extended portion  364  of the first metal terminal  316  and the second extended portion  384  of the second metal terminal  318  are used to space the first multilayer ceramic electronic component body  12  and the second multilayer ceramic electronic component body  14  away from the mounting substrate S on which the multilayer ceramic electronic component  10 C is mounted. Consequently, a stress caused by a difference in thermal expansion coefficient between the mounting substrate S and the multilayer ceramic electronic component  10 C, a stress caused by deflection of the mounting substrate S, or a mechanical distortion generated in the dielectric layer due to application of voltage is able to be absorbed by elastic deformation of the first extended portion  364  and the second extended portion  384 . As a result, problems such as a crack generated in the first multilayer ceramic electronic component body  12  and the second multilayer ceramic electronic component body  14  and the first external electrode  34   a  being peeled off from the first multilayer ceramic electronic component body  12  are able to be prevented, and generation of a noise (squeal) is able to be reduced by reducing or preventing transmission of vibration to the mounting substrate S through the first metal terminal  316  and the second metal terminal  318 . 
     The third extended portion  396  of the connection terminal  320  is connected to the third terminal bonding portion  392  and the fourth terminal bonding portion  394 , and extends such that a gap is provided between the first multilayer ceramic electronic component body  12  and the second multilayer ceramic electronic component body  14 . 
     The first mounting portion  366  of the first metal terminal  316  is connected to the first extended portion  364 , and mounted on the mounting substrate S. Specifically, the first mounting portion  366  is bent from the terminal end of the first extended portion  364 , and extends so as to be parallel or substantially parallel to the mounting surface. 
     The second mounting portion  386  of the second metal terminal  318  is connected to the second extended portion  384 , and mounted on the mounting substrate S. Specifically, the second mounting portion  386  is bent from the terminal end of the second extended portion  384 , and extends so as to be parallel or substantially parallel to the mounting surface. 
     In the third preferred embodiment, the first metal terminal  316 , the second metal terminal  318 , and the connection terminal  320  are preferably a plate-shaped frame terminal. Consequently, the bonding using the solder or the conductive adhesive is ensured, and surface mounting is able to be performed. However, the connection terminal  20  may be a lead terminal. 
     The first metal terminal  316  and the second metal terminal  318  preferably have a substantially U-shape in cross section. Thus, between the first external electrode  34   a  and the first metal terminal  316 , between the third external electrode  54   a  and the second metal terminal  318 , and between the mounting substrate S and the first metal terminal  316  and the second metal terminal  318 , the bonding area is increased, the contact resistance is decreased, and the physical bonding is ensured. As a result, resistance to the deflection of the mounting substrate S is able to be improved when the multilayer ceramic electronic component  10 C is mounted on the mounting substrate S. The shapes of the first metal terminal  316  and the second metal terminal  318  are not limited as long as the resistance to the deflection of the mounting substrate S is able to be improved.

     The first extended portion  564  of the first metal terminal  516  slightly extends outward in the direction connecting the first external electrode  34   a  and the second external electrode  34   b  from the first terminal bonding portion  562  such that a gap is provided between the he first extended portion  564  and the fourth end surface  44   f  of the second multilayer ceramic electronic component body  14 , namely, such that the first extended portion  564  does not contact with the second external electrode  54   b  disposed on the fourth end surface  44   f  of the second laminated body  44 , to be bent at right angles and extends in the direction of the mounting surface such that a gap is provided between the second multilayer ceramic electronic component body  14  disposed in a lower stage and the mounting surface of the mounting substrate S, and is connected to the first mounting portion  566 .

     The fourth extended portion  598  of the connection terminal  520  extends from the fourth terminal bonding portion  594  in the direction of the mounting surface on the extension line of the fourth terminal bonding portion  594  such that a gap is provided between the second multilayer ceramic electronic component body  14  and the mounting surface of the mounting substrate S, and is connected to the third mounting portion  600 . 
     The first extended portion  564  of the first metal terminal  516 , the second extended portion  584  of the second metal terminal  518 , and the fourth extended portion  598  of the connection terminal  520  are used to space the first multilayer ceramic electronic component body  12  and the second multilayer ceramic electronic component body  14  away from the mounting substrate S on which the multilayer ceramic electronic component  10 D is mounted. Consequently, a stress caused by a difference in thermal expansion coefficient between the mounting substrate S and the multilayer ceramic electronic component  10 D, a stress caused by deflection of the mounting substrate S, or the mechanical distortion generated in the dielectric layer due to the application of the voltage is able to be absorbed by the elastic deformation of the first extended portion  564 , the second extended portion  584 , and the fourth extended portion  598 . As a result, problems such as a crack generated in the first multilayer ceramic electronic component body  12  and the second multilayer ceramic electronic component body  14  and the second external electrode  34   b  being peeled off from the first multilayer ceramic electronic component body  12  are able to be prevented, and generation of a noise (squeal) is able to be reduced by reducing or preventing transmission of vibration to the mounting substrate S through the first metal terminal  516 , the second metal terminal  518 , and the connection terminal  520 . 
     The first mounting portion  566  of the first metal terminal  516  is connected to the first extended portion  564 , and mounted on the mounting substrate S. Specifically, the first mounting portion  566  is bent from the terminal end of the first extended portion  564 , and extends so as to be parallel or substantially parallel to the mounting surface. 
     The second mounting portion  586  of the second metal terminal  518  is connected to the second extended portion  584 , and mounted on the mounting substrate S.

     In the fourth preferred embodiment, the first metal terminal  516 , the second metal terminal  518 , and the connection terminal  520  are preferably plate-shaped frame terminals. Consequently, the bonding using the solder or the conductive adhesive is ensured, and surface mounting is able to be performed. 
     The first metal terminal  516 , the second metal terminal  518 , and the connection terminal  520  preferably have an L-shape or a substantially L-shape in cross section, for example. Thus, between the first external electrode  34   a  and the third external electrode  54   a  and the connection terminal  520 , between the second external electrode  34   b  and the first metal terminal  516 , between the fourth external electrode  54   b  and the second metal terminal  518 , and between the mounting substrate S and the first metal terminal  516 , the second metal terminal  518 , and the connection terminal  520 , the bonding area is increased, the contact resistance is decreased, and the physical bonding is ensured.

     The insulator  420  (indicated by a two-dot chain line) is preferably a resin, for example, and the resin is disposed between the first multilayer ceramic electronic component body  12  and the second multilayer ceramic electronic component body  14 , and covers the first multilayer ceramic electronic component body  12 , the second multilayer ceramic electronic component body  14 , a portion (a portion of the first terminal bonding portion  562  and a portion of the first extended portion  564 ) of the first metal terminal  516 , a portion (a portion of the second terminal bonding portion  582  and a portion of the second extended portion  584 ) of the second metal terminal  518 , and a portion (a portion of the third terminal bonding portion  592 , a portion of the fourth terminal bonding portion  594 , a portion of the third extended portion  596  and a portion of the fourth extended portion  598 ) of the third metal terminal  520  (hereinafter, referred to as exterior resin  420 ). 
     In the multilayer ceramic electronic component  10 D having the above-described configuration, the exterior resin  420  is only slightly larger than the width dimensions of the first multilayer ceramic electronic component body  12  and the second multilayer ceramic electronic component body  14 , so that the size of the multilayer ceramic electronic component  10 D is able to be reduced. 
     The edge-surface discharges of the second external electrode  34   b  and the fourth external electrode  54   b  are prevented by using the exterior resin  420 . The multilayer ceramic electronic component  10 D is covered with the resin, so that the gas (such as sulfur) corrosion resistance is improved. The bonding unit between the first metal terminal  516  and the second external electrode  34   b , the bonding unit between the second metal terminal  518  and the fourth external electrode  54   b , and the bonding unit between the connection terminal  520  and the first external electrode  34   a  and the third external electrode  54   a  are covered with the resin, so that the physical bonding stability and the heat resistance of the bonding unit are improved. 
     A preferred embodiment of a method for manufacturing a multilayer ceramic electronic component having the above-described structure will be described below. 
     First, a method for manufacturing the first multilayer ceramic electronic component body  12  and the second multilayer ceramic electronic component body  14  will be described. 
     A dielectric green sheet and an internal electrode conductive paste for forming an internal electrode are prepared. The dielectric green sheet and the internal electrode conductive paste include a binder and a solvent, and a known organic binder or organic solvent may preferably be used. 
     The internal electrode conductive paste is printed on the dielectric green sheet with a predetermined pattern by, for example, a screen printing method or a gravure printing method, and an internal electrode pattern is formed. 
     Subsequently, a predetermined number of dielectric green sheets for outer layers on which the internal electrode pattern is not printed are laminated, the dielectric green sheet on which the internal electrode pattern is printed is sequentially laminated on the dielectric green sheets for outer layers, and a predetermined number of dielectric layers for outer layers are laminated to produce a laminated sheet. 
     Subsequently, the laminated sheet is pressed in the laminating direction by isostatic pressing to prepare a laminated block. 
     Subsequently, the laminated block is cut into a predetermined shape having predetermined dimensions, and a raw laminated chip is cut out. At this point, a corner and a ridge of the raw laminated body may be rounded by barrel polishing or other suitable method. Subsequently, the cut raw laminated chip is fired to produce the laminated body. A firing temperature of the raw laminated chip depends on the material of the dielectric or the internal electrode conductive paste, but preferably the firing temperature is in a range of about 900° C. to about 1300° C., for example. 
     Subsequently, in order to form a baking layer of the external electrode, an external electrode conductive paste is applied to both end surfaces of the laminated body, and baked to form the baking layer of the external electrode. At this point, preferably the baking temperature is in a range of about 700° C. to about 900° C., for example. As necessary, at least one plating layer is formed on the surface of the baking layer, and the external electrode is formed to manufacture the multilayer ceramic electronic component. 
     Instead of forming the baking layer as the external electrode, a plating treatment may be directly applied on the surface of the laminated body to form an underlying plating film on the exposed portion of the internal electrode exposed from the end surface. Either electrolytic plating or electroless plating may be used as the plating treatment. However, in the electroless plating, a pretreatment with a catalyst, for example, is required in order to improve a plating deposition rate, and disadvantageously the process becomes complicated. Thus, usually the electrolytic plating is preferably used. Preferably, barrel plating is used as the plating method. 
     In the case in which a portion of the conductor of the external electrode is formed on the main surface of the laminated body, a surface conductor pattern may previously be printed on the dielectric green sheet of the outermost layer, and simultaneously fired together with the laminated body, or the surface conductors may be printed on the main surface of the fired laminated body, and then baked. As necessary, the upper plating layer is formed on the surface of the underlying plating film. 
     In this manner, a plating electrode is formed on the end surface of the laminated body. 
     A method for attaching the first metal terminal, the second metal terminal, and the connection terminal (hereinafter, referred to as metal terminal) to the laminated body will be described below. 
     The external terminal having a predetermined form is prepared. The first metal terminal and the second metal terminal are formed by bending. At this point, in the first preferred embodiment, the insulator  22  is prepared, the adhesive, such as the solder, for example, is applied to the insulator  22 , the external electrode of the laminated body, or the terminal bonding portion of the metal terminal, and the insulator  22  is provided between the first multilayer ceramic electronic component body  12  and the second multilayer ceramic electronic component body  14 , while the external electrode and the metal terminal are bonded to each other. In the case in which the solder is used as the adhesive, reflow is performed after the application of the solder, and the metal terminal is attached to the laminated body. 
     In the second to fourth preferred embodiments, the exterior resin is used to define and function as the insulator  22  of the first preferred embodiment, and the resin is molded and prepared by a transfer molding method. That is, after the laminated body to which the metal terminal is attached is placed in the mold, a thermosetting resin is injected into the mold while a pressure ranging from about 130° C. to about 150° C., for example, is applied. Subsequently, the thermosetting resin is cured at a temperature in a range of about 170° C. to about 190° C., for example. Subsequently, the mold is removed, and the multilayer ceramic electronic component having the exterior resin is taken out. 
     Samples of a multilayer ceramic capacitor were prepared, evaluation was performed to verify the improvement of the withstand voltage, and a dielectric breakdown voltage was measured. 
     An example and comparative examples were designed as follows. 
     In the Example, the multilayer ceramic electronic component  10 A of the first preferred embodiment in  FIGS. 1 to 8  was manufactured and evaluated. The multilayer ceramic capacitors of the following designs were used as the first multilayer ceramic electronic component body  12  and the second multilayer ceramic electronic component body  14 .

     Table 1 shows that the Comparative Example 1 has a low dielectric breakdown voltage and cannot be used in applications in which the high withstand voltage is required for a single capacitor. 
     In the Comparative Example 2, although the dielectric breakdown voltage is doubled with a single capacitor, the dielectric breakdown voltage is incompatible with the capacitance. 
     In the Comparative Example 3, although the dielectric breakdown voltage is compatible with the electrostatic capacitance, the mounting area is increased. 
     On the other hand, in the multilayer ceramic capacitor  10 A of the Example, the compatibility between the dielectric breakdown voltage and the electrostatic capacitance is able to be established while the increase in mounting area is prevented.
