CROSS REFERENCE TO RELATED APPLICATIONS 
     This application claims the benefit of priority to Japanese Patent Application No. 2018-192869 filed on Oct. 11, 2018 and Japanese Patent Application No. 2019-144855 filed on Aug. 6, 2019. The entire contents of these applications are hereby incorporated herein by reference. 
     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to an electronic component. 
     2. Description of the Related Art 
     A known electronic component includes a multilayer body in which inner electrodes and dielectric layers are alternately stacked, and an outer electrode that is electrically connected to the inner electrodes and that is formed on a surface of the multilayer body. 
     Such an electronic component disclosed in Japanese Unexamined Patent Application Publication No. 2016-86118 is a multilayer ceramic capacitor including outer electrodes that are disposed on both end surfaces of a multilayer body and outer terminals that are disposed on both side surfaces thereof. In the multilayer ceramic capacitor, signal inner electrodes that are extended to the end surfaces of the multilayer body and ground inner electrodes that are extended to the side surfaces of the multilayer body are alternately stacked with dielectric layers interposed therebetween. The outer electrodes that are disposed on the end surfaces of the multilayer body are electrically connected to the signal inner electrodes. Ground outer terminals that are disposed on the side surfaces of the multilayer body are electrically connected to the ground inner electrodes. 
     However, the multilayer ceramic capacitor disclosed in Japanese Unexamined Patent Application Publication No. 2016-86118 has a problem in that the size of an effective region in which each signal inner electrode and the corresponding ground inner electrode overlap in a stacking direction decreases because portions of the ground inner electrode are extended to the side surfaces of the multilayer body, and an electrostatic capacity decreases accordingly. 
     SUMMARY OF THE INVENTION 
     Preferred embodiments of the present invention provide electronic components that each include outer electrodes on side surfaces of a multilayer body and that enables an effective region in which inner electrodes overlap in the stacking direction to be enlarged. 
     According to a preferred embodiment of the present invention, an electronic component includes a multilayer body in which a plurality of inner electrodes and a plurality of dielectric layers are alternately stacked, and a plurality of outer electrodes that are electrically connected to the plurality of inner electrodes. The multilayer body includes a first main surface and a second main surface that are opposite to each other in a stacking direction, a first side surface and a second side surface that are opposite to each other in a width direction perpendicular or substantially perpendicular to the stacking direction, and a first end surface and a second end surface that are opposite to each other in a length direction perpendicular or substantially perpendicular to the stacking direction and the width direction. At least one of the plurality of outer electrodes is located on at least one of the first side surface or the second side surface of the multilayer body and is directly connected to the plurality of inner electrodes at positions spaced away from the at least one of the first side surface or the second side surface toward an inside of the multilayer body. 
     The multilayer body may include a margin portion in which the plurality of inner electrodes are not present when a section of the multilayer body including the length direction and the width direction is viewed in the stacking direction. Each of the plurality of outer electrodes may include a through section that extends through the margin portion and is directly connected to the plurality of inner electrodes by the through section. 
     The multilayer body may include an outer layer portion in which the plurality of inner electrodes are not present except for the margin portion when a section of the multilayer body including the width direction and the stacking direction is viewed in the length direction. Each of the plurality of outer electrodes may include the through section also at a height position in the stacking direction at which the outer layer portion is located. 
     The plurality of outer electrodes may be located on at least one of the first side surface and the second side surface. 
     The plurality of inner electrodes may include a first inner electrode and a second inner electrode. The plurality of outer electrodes may include at least one first outer electrode that is located on at least one of the first end surface or the second end surface of the multilayer body and that is connected to the first inner electrode, and at least one second outer electrode that is located on at least one of the first side surface or the second side surface of the multilayer body and that is connected to the second inner electrode. The second inner electrode is preferably not in contact with the at least one of the first end surface or the second end surface of the multilayer body on which the at least one first outer electrode is located. The first inner electrode may include a notch that overlaps, in the stacking direction, a connection between the second inner electrode and the at least one second outer electrode. 
     A dimension of the margin portion in the width direction may be no less than about 5 μm and no more than about 30 μm. 
     The margin portion may include margin layers that are stacked in the width direction. 
     The second inner electrode may include Si and Ti. A mole ratio of Si to Ti included in an end portion of the second inner electrode in the width direction may be larger than that in a central portion of the second inner electrode in the width direction. 
     The plurality of outer electrodes and the plurality of inner electrodes may include a common material including a dielectric material, and an amount of the common material that is included in the plurality of outer electrodes may be larger than an amount of the common material that is included in the plurality of inner electrodes. 
     An average particle diameter of a dielectric particle that is included in the plurality of dielectric layers that are located between the plurality of inner electrodes may be larger than an average particle diameter of a dielectric particle that is included in the margin portion. 
     A dimension, in the width direction, of one of the plurality of inner electrodes that is located at a central portion in the stacking direction may be larger than a dimension, in the width direction, of another inner electrode that is located at an outer portion in the stacking direction. 
     According to preferred embodiments of the present invention, at least one of the plurality of outer electrodes is located on at least one of the first side surface or the second side surface of the multilayer body and is directly connected to the plurality of inner electrodes at positions spaced away from the at least one of the first side surface or the second side surface toward the inside of the multilayer body. That is, it is not necessary for the plurality of inner electrodes to include extended portions that protrude in the width direction for connection to the at least one of the plurality of outer electrodes. Accordingly, an effective region in which the plurality of inner electrodes overlap in the stacking direction can be enlarged, and characteristics of the electronic component can be significantly improved. 
     The above and other elements, features, steps, characteristics and advantages of the present invention will become more apparent from the following detailed description of the preferred embodiments with reference to the attached drawings.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Preferred embodiments of the present invention will hereinafter be described in detail with reference to the drawings. In the following description, an example of an electronic component according to the present invention is a multilayer ceramic capacitor. The electronic component, however, is not limited to the multilayer ceramic capacitor and may be another electronic component, such as an inductor or a LC filter, for example. 
       FIG.  1    is a perspective view of an example of a multilayer ceramic capacitor  10  according to a preferred embodiment of the present invention.  FIG.  2    is a sectional view of the multilayer ceramic capacitor  10  shown in  FIG.  1    taken along line II-II.  FIG.  3    is a sectional view of the multilayer ceramic capacitor  10  shown in  FIG.  1    taken along line III-III. 
     As shown in  FIG.  1    to  FIG.  3   , the multilayer ceramic capacitor  10  preferably has a rectangular or substantially rectangular cuboid shape overall and includes a multilayer body  11  and outer electrodes  1  and  2  that are disposed on surfaces of the multilayer body  11 . 
     The multilayer body  11  includes a first end surface  15   a  and a second end surface  15   b  that are opposite to each other in a length direction L, a first main surface  16   a  and a second main surface  16   b  that are opposite to each other in a stacking direction T, and a first side surface  17   a  and a second side surface  17   b  that are opposite to each other in a width direction W. 
     The first end surface  15   a  and the second end surface  15   b  extend in the width direction W and the stacking direction T. The first main surface  16   a  and the second main surface  16   b  extend in the length direction L and the width direction W. The first side surface  17   a  and the second side surface  17   b  extend in the length direction L and the stacking direction T. 
     The outer electrodes  1  and  2  include first outer electrodes  1  and second outer electrodes  2 . According to the preferred embodiment, as shown in  FIG.  1   , two of the first outer electrodes  1  are disposed on the first end surface  15   a  and the second end surface  15   b  that are opposite to each other, and two of the second outer electrodes  2  are disposed on the first side surface  17   a  and the second side surface  17   b  that are opposite to each other. 
     Here, a direction in which the two first outer electrodes  1  are opposite to each other is defined as the length direction L of the multilayer ceramic capacitor  10 , and a direction in which first inner electrodes  13   a  and second inner electrodes  13   b , which are inner electrodes  13  described later, are stacked is defined as the stacking direction T, and a direction perpendicular or substantially perpendicular to the length direction L and the stacking direction T is defined as the width direction W. 
     Regarding the size of the multilayer ceramic capacitor  10 , for example, a dimension in the length direction L is preferably no less than about 0.2 mm and no more than about 3.2 mm, a dimension in the width direction W is no less than about 0.1 mm and no more than about 1.6 mm, and a dimension in the stacking direction T is no less than about 0.1 mm and no more than about 1.6 mm. The dimensions may have a tolerance of about ±10%. The relationship of magnitude among the dimension in the width direction W, the dimension in the length direction L, and the dimension in the stacking direction T of the multilayer ceramic capacitor  10  does not depend on the relationship of magnitude of the dimensions according to the preferred embodiment. For example, the dimension in the width direction W may be larger than the dimension in the length direction L. 
     The multilayer body  11  includes rounded corner portions and rounded ridge portions. Three surfaces of the multilayer body  11  intersect each other at the corner portions. Two surfaces of the multilayer body  11  intersect each other along the ridge portions. 
     As shown in  FIG.  2    and  FIG.  3   , the multilayer body  11  includes an inner layer portion  21 , outer layer portions  22 , and margin portions  23 . 
     The inner layer portion  21  includes dielectric layers  12 , the first inner electrodes  13   a , and the second inner electrodes  13   b . The dielectric layers  12 , the first inner electrodes  13   a , and the second inner electrodes  13   b  extend in the width direction W and the length direction L. 
     The dielectric layers  12  are interposed between the first inner electrodes  13   a  and the second inner electrodes  13   b . The first inner electrodes  13   a  and the second inner electrodes  13   b  are alternately stacked with the dielectric layers  12  interposed therebetween, and consequently, the inner layer portion  21  is defined. 
     Each dielectric layer  12  preferably includes, for example, dielectric ceramic particles each of which has a perovskite structure and includes a perovskite compound including Ba and Ti as a main component. The main component may include an additive of at least one of Si, Mg, Mn, or Ba, for example. The dielectric layer  12  may include a rare-earth element such as Dy, Y, or Ho, for example. The thickness of the dielectric layer  12  is preferably, for example, no less than about 0.3 μm and no more than about 1.0 μm. 
     The first inner electrodes  13   a  and the second inner electrodes  13   b  face each other in the stacking direction T with the dielectric layers  12  interposed therebetween. An electrostatic capacity is generated in regions in which the first inner electrodes  13   a  and the second inner electrodes  13   b  face each other with the dielectric layers  12  interposed therebetween. 
       FIG.  4 A  is a plan view of one of the dielectric layers  12  on which the corresponding first inner electrode  13   a  is provided.  FIG.  4 B  is a plan view of one of the dielectric layers  12  on which the corresponding second inner electrode  13   b  is provided. 
     As shown in  FIG.  4 A , each first inner electrode  13   a  includes notches  40  at central portions in the length direction L and along both of edges in the width direction W. That is, the first inner electrode  13   a  has a size smaller than that of each dielectric layer  12  due to the notches  40 . 
     The first inner electrodes  13   a  extend in the length direction L to the first end surface  15   a  and the second end surface  15   b  of the multilayer body  11 . The first inner electrodes  13   a  extend in the width direction W and are in contact with the margin portions  23  described later except for the notches  40 . 
     The second inner electrodes  13   b  are not in contact with the first end surface  15   a  and the second end surface  15   b  on which the first outer electrodes  1  are disposed. That is, as shown in  FIG.  4 B , the second inner electrodes  13   b  extend in the width direction W and are in contact with the margin portions  23  described later but do not extend in the length direction L to the first end surface  15   a  and the second end surface  15   b  of the multilayer body  11 . Accordingly, when the size of each dielectric layer  12  is considered as a standard, end portions of the second inner electrodes  13   b  in the length direction L are located a predetermined distance inward from the first end surface  15   a  and the second end surface  15   b  in the length direction L. 
     The second inner electrodes  13   b  are connected to the second outer electrodes  2  that are disposed on the first side surface  17   a  and the second side surface  17   b  of the multilayer body as described later but include no extended portions that protrude in the width direction W for connection to the second outer electrodes  2  as shown in  FIG.  4 B . As shown in  FIGS.  4 A and  4 B , the maximum dimension of each second inner electrode  13   b  in the width direction W is preferably equal or substantially equal to the maximum dimension of each first inner electrode  13   a  in the width direction W. 
     The first inner electrodes  13   a  and the second inner electrodes  13   b  preferably include, for example, Ni. The first inner electrodes  13   a  and the second inner electrodes  13   b  may include, for example, a metal such as Cu, Ag, Pd, an Ag—Pd alloy, or Au other than Ni. The first inner electrodes  13   a  and the second inner electrodes  13   b  preferably include, for example, a common material that is the same or substantially the same dielectric material as dielectric ceramics that is included in the dielectric layers  12 . 
     The first inner electrodes  13   a  and the second inner electrodes  13   b  preferably include, for example, Si and Ti. The mole ratio of Si to Ti included in end portions, in the width direction W, of the second inner electrodes  13   b  that have a uniform dimension in the width direction W is larger than that in central portions of the second inner electrodes  13   b  in the width direction W. That is, Si is segregated in the end portions of the second inner electrodes  13   b  in the width direction W. Similarly, Si is segregated in end portions of the first inner electrodes  13   a  in the width direction W. 
     The amounts of Ti and Si that are included in the second inner electrodes  13   b  can be obtained, for example, by a wave-length-dispersive X-ray spectroscopy (WDX) after the multilayer ceramic capacitor  10  is polished to expose the second inner electrodes  13   b.    
     The number of the inner electrodes  13  that are stacked and that include the first inner electrodes  13   a  and the second inner electrodes  13   b  is preferably, for example, no less than 20 and no more than 500. The thickness of each of the first inner electrodes  13   a  and the second inner electrodes  13   b  is preferably, for example, no less than about 0.1 μm and no more than about 0.8 μm. 
     According to the present preferred embodiment, as shown in  FIG.  3   , the end portions of the inner electrodes  13  are aligned in the stacking direction when a section of the multilayer ceramic capacitor  10  having the width direction W and the stacking direction T is viewed in the length direction L. That is, the dimensions of the inner electrodes  13  in the width direction W are equal or substantially equal to each other. 
     As shown in  FIG.  5   , the end portions of the inner electrode  13  in the width direction W at a central portion in the stacking direction T may protrude outward more than the end portions at outer portions in the stacking direction T. In other words, the dimensions, in the width direction W, of the inner electrodes  13  that are located at the outer portions in the stacking direction T are smaller than the dimension, in the width direction W, of the inner electrode  13  that is located at the central portion in the stacking direction T. A decrease in the dimensions, in the width direction W, of the inner electrodes  13  that are located at the outer portions in the stacking direction T enables distances from the ridge portions to the inner electrodes to be increased, and humidity resistance against water that enters from the ridge portions can be significantly improved. 
     For example, the dimensions of the inner electrodes  13  in the width direction W can be measured by the following method. A surface of the multilayer ceramic capacitor  10  having the width direction W and the stacking direction T is first exposed. In the following description, the surface having the width direction W and the stacking direction T is referred to as a WT section. Subsequently, the WT section is imaged with an optical microscope. The dimension, in the width direction W, of the inner electrode  13  that is located at the central portion in the stacking direction T and the dimensions, in the width direction W, of the inner electrodes  13  that are located at the outer portions in the stacking direction T are measured. The dimension, in the width direction W, of the inner electrode  13  that is located at the central portion in the stacking direction T and the dimensions, in the width direction W, of the inner electrodes  13  that are located at the outer portions in the stacking direction T are measured by calculating average values of measured values at three positions of the position of a central portion of the multilayer ceramic capacitor  10  in the length direction L, a position nearer than the central portion to the first end surface  15   a , and a position nearer than the central portion to the second end surface  15   b.    
     The outer layer portions  22  are disposed on both of the outsides of the inner layer portion  21  in the stacking direction T. That is, the inner layer portion  21  is interposed between the two outer layer portions  22  that are disposed on both of the outsides in the stacking direction T. In the outer layer portions  22 , the first inner electrodes  13   a  and the second inner electrodes  13   b  are not present except for the margin portions  23  described later when a section of the multilayer body  11  having the stacking direction T and the width direction W is viewed in the length direction L. 
     Each outer layer portion  22  includes a dielectric body including, for example, the same or substantially the same material as that of the dielectric layers  12 . A different dielectric material is also acceptable. The dimension of the outer layer portion  22  in the stacking direction T is preferably, for example, about 10 μm or more. 
     In the margin portions  23 , the first inner electrodes  13   a  and the second inner electrodes  13   b  are not present when a section of the multilayer body  11  having the length direction L and the width direction W is viewed in the stacking direction T. As shown in  FIG.  3   , the margin portions  23  are located on both of the outsides in the width direction W. That is, the inner layer portion  21  and the outer layer portions  22  are located between the two margin portions  23 , which are provided at both of the outsides of the inner layer portion  21  and the outer layer portions  22  in the width direction W. According to the present preferred embodiment, the margin portions  23  are located on both of the outsides in the width direction W but may be disposed on both of the outsides in the length direction L, that is, near the first end surface  15   a  and the second end surface  15   b.    
     According to the present preferred embodiment, each margin portion  23  includes margin layers that are stacked in the width direction W. Specifically, the margin portion  23  includes an outer margin layer  23   a  and an inner margin layer  23   b . The outer margin layer  23   a  is located near the first side surface  17   a  or the second side surface  17   b  of the multilayer body  11 . The inner margin layer  23   b  is located near the inner layer portion  21 , that is, at a position nearer than the outer margin layer  23   a  to the inside in the width direction W. 
     When each margin portion  23  includes the margin layers  23   a  and  23   b , boundaries therebetween can be readily checked by observing differences in sinterability between the outer margin layer  23   a  and the inner margin layer  23   b  with an optical microscope. That is, there is a boundary line between the outer margin layer  23   a  and the inner margin layer  23   b.    
     The dimension of each margin portion  23  in the width direction W is preferably, for example, no less than about 5 μm and no more than about 100 μm. According to the present preferred embodiment, the dimension of the outer margin layer  23   a  in the width direction W is larger than the dimension of the inner margin layer  23   b  in the width direction W. 
     The dimension of each margin portion  23  in the width direction W refers to an average dimension that is calculated on the basis of measured values of the dimension of the margin portion  23  at positions in the stacking direction T. A method of measuring the dimension of the margin portion  23  in the width direction W is as follows. 
     A WT section of the multilayer ceramic capacitor  10  having the width direction W and the stacking direction T is first exposed. Subsequently, an optical microscope images with the end portions of the first inner electrodes  13   a  and the second inner electrodes  13   b  in the width direction W in the WT section within the same or substantially the same field of view as a corresponding one of the two margin portions  23  that are located on both of the outsides in the width direction W. Three portions of an upper portion, a central portion, and a lower portion in the stacking direction T are imaged. Parallel lines in the width direction W are drawn on the upper portion, the central portion, and the lower portion from the end portions of the first inner electrodes  13   a  and the second inner electrodes  13   b  in the width direction W toward the first side surface  17   a  or the second side surface  17   b , and the lengths of the lines are measured. The average values of the measured lengths of the lines are calculated for the upper portion, the central portion, and the lower portion. The average values are averaged to obtain the dimension of the margin portion  23  in the width direction W. 
     Each margin portion  23  includes a dielectric body preferably including, for example, a dielectric ceramic material that includes BaTiO 3  as a main component and that has a perovskite structure. The main component preferably includes an additive of Si, for example. 
     The average particle diameter of the dielectric particles that are included in the dielectric layers  12  that are interposed between the first inner electrodes  13   a  and the second inner electrodes  13   b  is larger than the average particle diameter of the dielectric particles that are included in the margin portions  23 . The average particle diameter of the dielectric particles in a central portion of the multilayer body  11  in the width direction W and the stacking direction T is compared with the average particle diameter of the dielectric particles in central portions of the margin portions  23  in the width direction W and the stacking direction T after the multilayer body  11  is polished up to a central portion in the length direction L. The average particle diameter of the dielectric particles is calculated by imaging the exposed section with the settings of the SEM including a magnification of 5000, an acceleration voltage of about 15 kV, and a field of view of about 30 μm× about 30 μm, the circumferences of all of the dielectric particles are recognized by image-processing software to calculate an area, and the area is regarded as the area of a circle. The diameters of all of the dielectric particles that are within the range of the image except for a dielectric particle that is partially imaged are measured. The average value thereof is determined to be the average particle diameter of the dielectric particles. 
     The outer margin layer  23   a  includes Si in an amount larger than that in the inner margin layer  23   b . That is, the mole ratio of Si to Ti in the outer margin layer  23   a  is higher than the mole ratio of Si to Ti in the inner margin layer  23   b . For example, the mole ratio of Si to Ti in the outer margin layer  23   a  is preferably no less than about 3.5 and no more than about 6.0. The mole ratio of Si to Ti in the inner margin layer is preferably no less than about 0.02 and no more than about 3.5. The mole ratio can be measured by WDX analysis or a TEM. 
     Since Si acts as a sintering additive, the outer margin layer  23   a  that is obtained by firing when the multilayer ceramic capacitor  10  is manufactured has a finer structure than that of the inner margin layer  23   b . Accordingly, the strength of the margin portions  23  is able to be increased. Accordingly, the margin portions  23  are unlikely to crack and chip, and water is prevented from entering the inside. 
     The margin portions  23  can be formed, for example, by manufacturing a multilayer body chip that is to be the inner layer portion  21  and the outer layer portions  22  after firing, and ceramic green sheets are subsequently attached to both of side surfaces of the multilayer body chip and fired. Ceramic slurry that is to be the ceramic green sheets may be applied to both of the side surfaces. 
     The first outer electrodes  1  are disposed on the first end surface  15   a  and the second end surface  15   b  of the multilayer body  11 . The first outer electrode  1  that is disposed near the first end surface  15   a  is disposed on the entire or substantially the entire first end surface  15   a  and extends from the first end surface  15   a  along the first main surface  16   a , the second main surface  16   b , the first side surface  17   a , and the second side surface  17   b . The first outer electrode  1  that is disposed near the second end surface  15   b  is disposed on the entire or substantially the entire second end surface  15   b  and extends from the second end surface  15   b  along the first main surface  16   a , the second main surface  16   b , the first side surface  17   a , and the second side surface  17   b.    
       FIG.  6 A  is a sectional view of the multilayer ceramic capacitor  10  taken along a plane including one of the first inner electrodes  13   a .  FIG.  6 B  is a sectional view thereof taken along a plane including one of the second inner electrodes  13   b.    
     As shown in  FIG.  6 A , the first outer electrodes  1  are directly connected to the first inner electrodes  13   a  along the first end surface  15   a  and the second end surface  15   b  of the multilayer body  11  and are electrically connected to the first inner electrodes  13   a . As shown in  FIG.  6 B , the first outer electrodes  1  are not electrically connected to the second inner electrodes  13   b.    
     In the specification, the outer electrodes being directly connected to the inner electrodes indicates that the outer electrodes and the inner electrodes are connected to each other with the outer electrodes and the inner electrodes being in contact with each other. 
     Each first outer electrode  1  preferably includes a metal such as, for example, Ni, Cu, Ag, Pd, an Ag—Pd alloy, or Au. The first outer electrode  1  preferably includes, for example, the common material that is the same or substantially the same dielectric material as the dielectric ceramics that is included in the dielectric layers  12 . The common material provides a behavior of shrinkage of the first outer electrode  1  during firing that is the same as, or similar to, a behavior of shrinkage of the multilayer body  11  and prevents the first outer electrode  1  from being separated from the multilayer body  11 . 
     The second outer electrodes  2  are disposed on the first side surface  17   a  and the second side surface  17   b  of the multilayer body  11 . The second outer electrode  2  that is disposed near the first side surface  17   a  is disposed on a central portion of the first side surface  17   a  in the length direction L and extends from the first side surface  17   a  along the first main surface  16   a  and the second main surface  16   b . The second outer electrode  2  that is disposed near the second side surface  17   b  is disposed on a central portion of the second side surface  17   b  in the length direction L and extends from the second side surface  17   b  along the first main surface  16   a  and the second main surface  16   b.    
     The positions of the second outer electrodes  2  that are disposed on the first side surface  17   a  and the second side surface  17   b  are not limited to the positions of the central portions in the length direction L. 
     As shown in  FIGS.  6 A and  6 B , the second outer electrodes  2  that are disposed on the first side surface  17   a  and the second side surface  17   b  of the multilayer body  11  include respective surface portions  2   a  that are located on the surfaces of the multilayer body  11  and respective through sections  2   b  that extend through the margin portions  23 . As shown in  FIG.  6 B , the through sections  2   b  are located between the first side surface  17   a  or the second side surface  17   b  of the multilayer body  11  and the end portions of the second inner electrodes  13   b  in the width direction W. The second outer electrodes  2  are directly connected to the second inner electrodes  13   b  at positions spaced away from the first side surface  17   a  and the second side surface  17   b  toward the inside of the multilayer body  11  by the through sections  2   b  and are electrically connected to the second inner electrodes  13   b . Each through section  2   b  has a size of at least about 10 μm or more. At least the through sections that are connected to the corresponding second inner electrodes  13   b  face each other in the stacking direction. 
     Each first inner electrode  13   a  includes the notches  40  on the central portion in the length direction L and along both of the edges in the width direction W, as described above. The notches  40  overlap connections between the second inner electrodes  13   b  and the second outer electrodes  2  in the stacking direction T. As shown in  FIG.  6 A , both ends of the notches  40  in the length direction L are located nearer than both ends of the through sections  2   b  of the second outer electrodes  2  in the length direction L to the outside. With this structure, the second outer electrodes  2  are not electrically connected to the first inner electrodes  13   a.    
       FIG.  7    is a sectional view of the multilayer ceramic capacitor  10  taken along a plane including one of the outer layer portions  22 . As shown in  FIG.  7   , the second outer electrodes  2  include the through sections  2   b  that extend through the margin portions  23  not only at height positions in the stacking direction T at which the second inner electrodes  13   b  are disposed, but also at height positions at which the second inner electrodes  13   b  are not disposed but the outer layer portions  22  are disposed. 
     That is, the through sections  2   b  of the second outer electrodes  2  extend through the margin portions  23  from the first main surface  16   a  of the multilayer body  11  to the second main surface  16   b  when viewed in the stacking direction T. 
     Each second outer electrode  2  preferably includes a metal such as, for example, Ni, Cu, Ag, Pd, an Ag—Pd alloy, or Au. The second outer electrode  2  preferably includes, for example, the common material that is the same or substantially the same ceramic material as the dielectric ceramics that is included in the dielectric layers  12 . The common material provides a behavior of shrinkage of the second outer electrode  2  during firing that is the same as, or similar to, a behavior of shrinkage of the multilayer body  11  and prevents the second outer electrode  2  from being separated from the multilayer body  11 . 
     The first outer electrodes  1  and the second outer electrodes  2  can be formed, for example, by being simultaneously fired together with the first inner electrodes  13   a  and the second inner electrodes  13   b , that is, by co-firing. In this case, the first outer electrodes  1  and the second outer electrodes  2  each have a structure that is formed by being simultaneously fired. 
     In the case of formation by co-firing, for example, the first inner electrodes  13   a  and the second inner electrodes  13   b  can include Ni, and the first outer electrodes  1  and the second outer electrodes  2  can also include Ni. The formation by co-firing increases the strength of joints between the first inner electrodes  13   a  and the first outer electrodes  1  and increases the strength of joints between the second inner electrodes  13   b  and the second outer electrodes  2 . 
     In the case where the first outer electrodes  1  and the second outer electrodes  2  are formed by co-firing, the amount of the common material that is included in the first outer electrodes  1  and the second outer electrodes  2  is preferably, for example, larger than the amount of the common material that is included in the first inner electrodes  13   a  and the second inner electrodes  13   b  in order to increase the strength of the joints between the first outer electrodes  1  and the multilayer body  11  and between the second outer electrodes  2  and the multilayer body  11 . For example, the amount of the common material that is included in the first outer electrodes  1  and the second outer electrodes  2  by wt % is preferably, for example, equal to or more than about 3 times the amount of the common material that is included in the first inner electrodes  13   a  and the second inner electrodes  13   b.    
     The kind of elements that are included in the first outer electrodes  1  and the second outer electrodes  2  can be checked by transmission electron microscope-energy-dispersive X-ray spectroscopy (TEM-EDX) elemental analysis. 
     In the case where the first outer electrodes  1  and the second outer electrodes  2  are formed as Ni layers, the content of a ceramic material in each Ni layer is preferably, for example, no less than about 25 area % and no more than about 40 area %. The content of the ceramic material in the Ni layer being about 25 area % or more indicates that the ceramic material is included in a predetermined amount or more in the Ni layer. The outer electrodes  1  and  2  that include the corresponding Ni layer that include the ceramic material in a predetermined amount or more can be formed by simultaneously firing outer electrode paste when the multilayer body is fired. The content of the ceramic material in the Ni layer is more preferably, for example, about 40 area % or less. 
     The content of the ceramic material in each Ni layer is measured by the following method with the wave-length-dispersive X-ray spectroscopy (WDX). A section of a central portion of the multilayer ceramic capacitor  10  in the width direction W is first exposed. A central portion of the Ni layer in the thickness direction in a central portion of the multilayer body  11  in the stacking direction T is enlarged to 10000 times. The field of view of an enlarged region has a range of about 6 μm× about 8 μm. The enlarged region is mapped by WDX. An area ratio is measured from an image that is obtained by mapping. 
     Each first outer electrode  1  preferably, for example, includes a Ni layer  1   d , a first plating layer  1   e , a second plating layer  1   f , and a third plating layer  1   g  that are provided in this order from a position near the first end surface  15   a  or the second end surface  15   b  of the multilayer body  11 . Similarly, each second outer electrode  2  preferably includes, for example, a Ni layer  2   d , a first plating layer  2   e , a second plating layer  2   f , and a third plating layer  2   g  in this order from a position near the first side surface  17   a  or the second side surface  17   b  of the multilayer body  11 . The first plating layers  1   e  and  2   e  are preferably formed, for example, by Cu plating. The second plating layers  1   f  and  2   f  are preferably formed, for example, by Ni plating. The third plating layers  1   g  and  2   g  are preferably formed, for example, by Sn plating. Only the second plating layers  1   f  and  2   f  and the third plating layers  1   g  and  2   g  suffice. The first outer electrode  1  may include a conductive resin layer that includes conductive particles and resin between the Ni layer  1   d  and the first plating layer  1   e . Similarly, the second outer electrode  2  may include a conductive resin layer that includes conductive particles and resin between the Ni layer  2   d  and the first plating layer  2   e . Examples of the conductive particles include metal particles such as Cu particles, Ag particles, and Ni particles. 
     In the case where the second outer electrodes  2  are formed by co-firing, the boundaries between the second outer electrodes  2  and the second inner electrodes  13   b  can be checked by checking the amounts of the common materials that are included therein because the amount of the common material that is included in the second outer electrodes  2  differs from the amount of the common material that is included in the second inner electrodes  13   b . In addition, whether the second inner electrodes  13   b  protrude outward in the width direction W and are connected to the second outer electrodes  2 , or whether the second outer electrodes  2  extend inward in the width direction W and are connected to the second inner electrodes  13   b  can be grasped by checking the boundaries between the second outer electrodes  2  and the second inner electrodes  13   b.    
     The first outer electrodes  1  and the second outer electrodes  2  can also be formed by firing conductive paste that is applied to the multilayer body  11 , that is, by post-firing. In the case where the first outer electrodes  1  and the second outer electrodes  2  are formed by post-firing, the first outer electrodes  1  and the second outer electrodes  2  preferably includes glass in a larger amount than those in the first inner electrodes  13   a  and the second inner electrodes  13   b . Accordingly, the boundaries between the second outer electrodes  2  and the second inner electrodes  13   b  can be checked by checking the amounts of glass included in the second outer electrodes  2  and the second inner electrodes  13   b . In addition, whether the second inner electrodes  13   b  protrude outward in the width direction W and are connected to the second outer electrodes  2 , or whether the second outer electrodes  2  extend inward in the width direction W and are connected to the second inner electrodes  13   b  can be grasped by checking the boundaries between the second outer electrodes  2  and the second inner electrodes  13   b.    
     The outer electrode paste that forms the first outer electrodes  1  and the second outer electrodes  2  is preferably applied, for example, by a roller in order to inhibit air to enter the inside. 
     In the multilayer ceramic capacitor  10  according to the present preferred embodiment, the second outer electrodes  2  that are disposed on the first side surface  17   a  and the second side surface  17   b  of the multilayer body  11  are directly connected to the second inner electrodes  13   b  at positions spaced away from the first side surface  17   a  and the second side surface  17   b  toward the inside of the multilayer body  11  as described above. That is, it is not necessary for the second inner electrodes  13   b  to include extended portions that protrude in the width direction W for connection to the second outer electrodes  2 . Accordingly, effective regions in which the first inner electrodes  13   a  and the second inner electrodes  13   b  overlap in the stacking direction T can be enlarged, and the electrostatic capacity per volume can be increased. 
     With the above structure, each margin portion  23  protects the effective regions in the width direction W, and the dimension of the margin portion  23  in the width direction can be decreased. Accordingly, the size of the multilayer ceramic capacitor  10  can be decreased, and the ESL of the multilayer ceramic capacitor  10  can be decreased. 
     In particular, the second outer electrodes  2  of the multilayer ceramic capacitor  10  according to the present preferred embodiment include the through sections  2   b  that extend through the margin portions  23  and are directly connected to the second inner electrodes  13   b  by the through sections  2   b . With this structure, the second inner electrodes  13   b  include no extended portions that protrude in the width direction W for connection to the second outer electrodes  2 , and the second inner electrodes  13   b  and the second outer electrodes  2  can be connected to each other. 
     In a multilayer ceramic capacitor that corresponds to an electronic component according to a preferred embodiment of the present invention, at least one of outer electrodes is disposed on at least one of a first side surface or a second side surface of a multilayer body and is directly connected to inner electrodes at positions spaced away from the at least one of the first side surface or the second side surface toward the inside of the multilayer body. The multilayer ceramic capacitor  10  according to the preferred embodiment described above is an example of the multilayer ceramic capacitor that has such a structure. Another example of the multilayer ceramic capacitor that has the structure of an electronic component according to the present invention other than the above multilayer ceramic capacitor  10  will be described below.

FIG.  12 B  is a sectional view thereof taken along a plane including one of the second inner electrodes  13   b .  FIGS.  12 A and  12 B , each margin portion  23  is shown as a single layer but may include margin layers. 
     Two of the first outer electrodes  1  and two of the second outer electrodes  2  are alternately disposed on the first side surface  17   a . Two of the first outer electrodes  1  and two of the second outer electrodes  2  are alternately disposed on the second side surface  17   b  of the multilayer body  11 . One of the first outer electrodes  1  is disposed on the first end surface  15   a , and the other first outer electrode is disposed on the second end surface  15   b.    
     As shown in  FIGS.  12 A and  12 B , the first outer electrodes  1  that are disposed on the first side surface  17   a  and the second side surface  17   b  of the multilayer body  11  include the respective surface portions  1   a  that are located on the surfaces of the multilayer body  11  and the respective through sections  1   b  that extend through the margin portions  23 . As shown in  FIGS.  12 A and  12 B , the second outer electrodes  2  that are disposed on the first side surface  17   a  and the second side surface  17   b  of the multilayer body  11  include the respective surface portions  2   a  that are located on the surfaces of the multilayer body  11  and the respective through sections  2   b  that extend through the margin portions  23 . 
     As shown in  FIG.  12 A , each first inner electrode  13   a  has the notches  40  that overlap connections between the second inner electrodes  13   b  and the second outer electrodes  2  in the stacking direction T. As shown in  FIG.  12 B , each second inner electrode  13   b  has the notches  40  that overlap connections between the first inner electrodes  13   a  and the first outer electrodes  1  in the stacking direction T. 
     With the above structure, the first outer electrodes  1  are connected to the first inner electrodes  13   a  as shown in  FIG.  12 A  but are not connected to the second inner electrodes  13   b  as shown in  FIG.  12 B . The second outer electrodes  2  are connected to the second inner electrodes  13   b  as shown in  FIG.  12 B  but are not connected to the first inner electrodes  13   a  as shown in  FIG.  12 A . 
     In the multilayer ceramic capacitor  10 E shown in  FIGS.  12 A and  12 B , the first inner electrodes  13   a  include no extended portions that protrude in the width direction W for connection to the first outer electrodes  1 , and the second inner electrodes  13   b  include no extended portions that protrude in the width direction W for connection to the second outer electrodes  2 . 
     The present invention is not limited to the above-described preferred embodiments. Various applications and additional modifications can be made within the scope of the present invention. 
     For example, in the above multilayer ceramic capacitor  10 , each through section  2   b  of the second outer electrodes  2  may have a dimension near the inner layer portion  21  in the length direction L that is smaller than those near the first side surface  17   a  and the second side surface  17   b . Similarly, in the structures according to the first to fifth modifications, each through section of the outer electrodes may have a dimension near the inner layer portion  21  in the length direction L that is smaller than those near the side surfaces. 
     In the description according to the preferred embodiments, each margin portion  23  includes the margin layers  23   a  and  23   b  that are stacked in the width direction W. However, the margin portion  23  may be defined by a single layer.
