Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a continuation of U.S. application Ser. No. 15/741,114, filed Dec. 29, 2017; which is the U.S. national stage application of International Patent Application No. PCT/KR2016/007006, filed Jun. 30, 2016; which claims priority to Korean Application Nos. 10-2015-0092714, filed Jun. 30, 2015; and 10-2015-0110871, filed Aug. 6, 2015; all of which are incorporated herein by reference in their entirety. 
    
    
     TECHNICAL FIELD 
     Embodiments relate to a lens moving apparatus, a camera module including the lens moving apparatus and a portable device including the lens moving apparatus. 
     BACKGROUND ART 
     The disclosure of this section is intended to merely provide background information relating to the embodiments and does not necessarily constitute the related art. 
     Recently, information technology products such as cellular phones, smart phones, tablet PCs and notebook PCs, in which ultracompact digital cameras are incorporated, are being actively developed. 
     A camera module mounted in a small-sized electronic product, such as a smart phone, may be frequently subjected to shocks during use. In addition, the camera module may minutely shake due to the trembling of a user&#39;s hand while taking a photography. Therefore, there is an urgent necessity for technology capable of installing an optical image stabilizer in the camera module. 
     When a device, an element or the like, which is required to realize such handshake correction, is subjected to external shocks, the component may be separated from a camera module or a lens moving apparatus included in the camera module, thereby causing breakage, malfunction or the like of the camera module. Accordingly, there is a need to mend the problem. 
     It is difficult to adopt voice coil motor (VCM) technology, which is typically used in conventional camera modules, for use in an ultracompact camera module, which aims at achieving low power consumption, and thus research regarding the technology has been actively undertaken. 
     A lens moving apparatus of a camera module may include a base and a printed circuit board for controlling the base. The printed circuit board of the les moving apparatus of the camera module may be bent by 90 degrees at opposite ends thereof, and may be attached to the base. Here, there is a problem in that the printed circuit board is raised up from the base during the attachment procedure. 
     In addition, when an adhesive member is provided on surfaces of the printed circuit board and the base that come into contact with each other in a surface-contact manner, to overcome this problem, there is an additional problem in that the adhesive member flows into a mounting recess during the attachment between the printed circuit board and the base. 
     Technical Object 
     Accordingly, embodiments relate to a lens moving apparatus in which a device, parts and the like for fulfilling a handshake correction function are firmly coupled with each other, and a camera module including the lens moving apparatus. 
     An object of the embodiments is to provide a lens moving apparatus designed to inhibit a printed circuit board from being raised up from a base, and a camera module including the lens moving apparatus. 
     In addition, another object of the embodiments is to provide a lens moving apparatus, which is provided with a base including a stepped portion for accommodating an adhesive member leaking from between a printed circuit board and the base in a procedure of attaching the printed circuit board to the base, and a camera module including the lens moving apparatus. 
     The technical goal to be accomplished by the embodiments is not limited to the above-mentioned technical goal, and other technical goals, which are not mentioned above, will be apparently understood by one of ordinary skill in the art to which the embodiments belong.

     Best Mode 
     Hereinafter, embodiments will be described with reference to the attached drawings. Since the embodiments may be altered in various ways, specific embodiments illustrated in the drawings will be described in detail. However, the embodiments should not be construed as being limited only to the specific embodiments set forth herein, but should be understood to cover all modifications, equivalents or alternatives falling within the idea and technical scope of the disclosure. The sizes and shapes of elements shown in the drawings may be exaggerated for clarity and convenience of explanation. 
     It will be understood that although the terms “first”, “second”, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element. In addition, it should be understood that terms that are particularly defined in consideration of construction and operation of the embodiments are intended to explain the embodiments and should not be construed as limiting the scope of the embodiments. 
     In the following description of the embodiments, it will be understood that, when an element is referred to as being formed “on” or “under” the another element, it can be directly “on” or “under” the other element, or can be indirectly disposed with one or more intervening elements therebetween. In addition, it will also be understood that “on” or “under” the element may mean an upward direction or a downward direction based on the element. 
     In addition, the relative terms “top/upper/above”, “bottom/lower/under” and the like in the description and in the claims may be used to distinguish between any one substance or element and other substances or elements and are not necessarily intended to describe any physical or logical relationship between the substances or elements or a particular order. 
     For reference, in the respective drawings, a rectangular coordinate system (x, y, z) may be used. In the drawings, the x-axis and the y-axis indicate a plane perpendicular to the optical axis, and for convenience, the optical axis (z-axis) direction may be referred to as a first direction, the x-axis direction may be referred to as a second direction, and the y-axis direction may be referred to as a third direction. 
     An optical image stabilizing apparatus, which is applied to compact camera modules of mobile devices such as smart phones or tablet PCs, refers to an apparatus configured to inhibit the contour of an image captured upon still image shooting from not being clearly formed due to vibrations caused by the trembling of user&#39;s hand. 
     In addition, an autofocusing device is configured to automatically focus the subject image on the surface of an image sensor. The optical image stabilizing apparatus and the autofocusing device may be configured in various manners. The lens moving apparatus according to the embodiments may perform the optical image stabilizing and/or autofocusing operations in such a manner as to move an optical module composed of a plurality of lenses in a first direction or in a direction perpendicular to the first direction. 
     As shown in  FIG.  2   , the lens moving apparatus according to an embodiment may include a movable unit. The movable unit may fulfill the functions of autofocusing and handshake correction for a lens. The movable unit may include a bobbin  110 , a first coil  120 , first magnets  130 , a housing  140 , an upper elastic member  150  and a lower elastic member  160 . 
     The bobbin  110  may be disposed in the first magnets  130 , and may be provided on the outer circumferential surface thereof with the first coil. The bobbin  110  may be mounted so as to be reciprocated in a first direction in the internal space of the housing  140  by electromagnetic interaction between the first magnets  130  and the first coil  120 . The first coil  120  may be provided on the outer surface of the bobbin  110  so as to electromagnetically interact with the first magnets  130 . 
     The bobbin  110  may be moved in the first direction while being elastically supported by the upper and lower elastic members  150  and  160 , thereby fulfilling the autofocusing function. 
     The bobbin  110  may include a lens barrel (not shown) into which at least one lens is mounted. The lens barrel may be internally coupled with the bobbin  110  in various manners. 
     In an example, the bobbin  110  may be provided on the inner surface thereof with a female threaded portion, and the lens barrel may be provided on the outer surface thereof with a male threaded portion corresponding to the female threaded portion, whereby the lens barrel may be coupled with the bobbin  110  by means of threaded engagement therebetween. However, the coupling between the lens barrel and the bobbin  110  is not limited thereto, and the lens barrel may be directly coupled with the inside of the bobbin  110  in a manner other than the threaded engagement, in which case the female threaded portion is not provided on the inner surface of the bobbin  110 . Alternatively, one or more lenses may be integrally formed with the bobbin  110 , without using the lens barrel. 
     The lens, which is coupled with the lens barrel, may be composed of a single lens, or two or more lenses constituting an optical system. 
     The autofocusing function may be controlled by changing the direction of current, or may be fulfilled by the action of moving the bobbin  110  in the first direction. For example, the bobbin  110  may be moved upward from its initial position upon the application of forward current, and may be moved downward upon the application of reverse current. The distance by which the bobbin  110  moves in one direction from the initial position may be increased or decreased by controlling the amount of current flowing in one direction. 
     The bobbin  110  may be provided on upper and lower surfaces thereof with a plurality of upper support protrusions and a plurality of lower support protrusions, respectively. The upper support protrusions may be configured to have a circular cylindrical shape or a rectangular column shape, and may serve to couple or secure the upper elastic member  150  thereto. The lower support protrusions may also be configured to have a circular cylindrical shape or a rectangular column shape, and may serve to couple or secure the lower elastic member  160  thereto, like the upper support protrusions. 
     The upper elastic member  150  may have therein through holes corresponding to the upper support protrusions, and the lower elastic member  160  may have therein through holes corresponding to the lower support protrusions. The respective support protrusions and the corresponding through holes may be fixedly coupled with each other by means of thermal fusion or an adhesive such as epoxy. 
     The housing  140  may function to support the first magnets  130 . As shown in  FIGS.  1  and  2   , in an embodiment, the housing  140  may be configured to have a hollow column, for example, an approximately rectangular hollow column capable of supporting the first magnets  130 . Each lateral side of the housing  140  may be provided with the first magnet  130  and support members  220  secured thereto. 
     As described above, the housing  140  may be provided therein with the bobbin  110 , which is moved in the first direction under the guidance of the elastic members  150  and  160 . In this embodiment, the first magnets  130  may be disposed at the corner regions of the housing  140 , and the support members  220  may be disposed on the lateral side surfaces of the housing  140 . 
     The upper elastic member  150  may be disposed on the bobbin  110 , and the lower elastic member  160  may be disposed under the bobbin  110 . The upper elastic member  150  and the lower elastic member  160  may elastically support the upward or downward movement of the bobbin  110  in the first direction. The upper elastic member  150  and the lower elastic member  160  may be constituted by a leaf spring. 
     As shown in  FIG.  2   , the upper elastic member  150  may be composed of a pair of elastic members, which are separated from each other. By virtue of the dual partitioning structure, current having different polarities or different electric powers may be applied to the respective partitioned elastic members of the upper elastic member  150 . In a modification, the lower elastic member  160  may also be composed of a pair of partitioned elastic members, and the upper elastic member  150  may be configured to have an integral structure. 
     The upper elastic member  150 , the lower elastic member  160 , the bobbin  110  and the housing  140  may be assembled to one another by means of thermal fusion and/or bonding using an adhesive or the like. Here, the components may be first coupled with one another by means of thermal fusion, and may then be finally coupled with one another by means of bonding using an adhesive. 
     The base  210  may be disposed under the bobbin  110 , and may be configured to have an approximately rectangular shape. A printed circuit board  250  may be mounted on the base  210 , and lower portions of the support members  220  may be coupled with the base  210 . The base  210  may be provided in the upper surface thereof with mounting grooves  214  into which the support members  220  are fitted. An adhesive may be applied to the mounting grooves  214  to immobilize the support members  220 . 
     The regions of the base  210  that face terminal members  253  of the printed circuit board  250  may be provided with respective support recesses having a size corresponding to that of the terminal members  253 . The support recesses may be recessed from the outer circumferential surface of the base  210  by a predetermined depth such that the terminal members  253  do not protrude outward from the outer circumferential surface of the base  210  or such that the extent to which the terminal members  253  protrude can be controlled. 
     The support members  220  are disposed on the lateral sides of the housing  140  such that the upper sides of the support members  220  are coupled with the housing  140  and the lower sides of the support members  220  are coupled with the base  210 . The support members  220  may support the bobbin  110  and the housing  140  in such a manner as to allow the bobbin  110  and the housing  140  to move in the second and third directions, perpendicular to the first direction. The support members  220  may be conductively connected to the first coil  120 . 
     The upper elastic member  150  may apply current to the first coil  120  through the support members  220  conductively connected thereto. Although the support members  220  are illustrated in  FIG.  2    as being embodied as plate-shaped support members according to an embodiment, the support members  220  are not limited thereto. In other words, the support members  220  may be configured to have a wire shape. 
     Second coils  230  may move the housing  140  in the second and/or third directions to perform the handshake correction by virtue of electromagnetic interaction with the first magnets  130 . 
     The second or third direction may include not only the x-axis direction and the y-axis direction but also a direction which is substantially close to the x-axis direction or the y-axis direction. In other words, in terms of driving in the embodiments, although a housing  140  may move in a direction parallel to the x-axis or the y-axis, the housing may move in a direction which is slightly oblique with respect to the x-axis or the y-axis in the state of being supported by a support member  220 . 
     The first magnets  130  are required to be disposed at positions corresponding to the second coils  230 . 
     The second coils  230  may be disposed so as to face the first magnets  130 , which are secured to the housing  140 . In one embodiment, the second coils  230  may be disposed outside the first magnets  130 , or may be disposed under the first magnets  130  so as to be spaced apart from the first magnets  130  by a predetermined distance. 
     According to the embodiment, although a total of four second coils  230  may be disposed such that one thereof is disposed on each corner of a circuit member  231 , the disclosure is not limited thereto. Only two second coils  230 , that is, one second coil for movement in the second direction and one second coil for movement in the third direction, may be provided, or a total of more than four second coils  230  may be provided. 
     In the embodiment, although circuit patterns having the shape of the second coils  230  are formed on the circuit member  231  and additional second coils are disposed on the circuit member  231 , the disclosure is not limited thereto. Alternatively, only additional second coils  230  may be disposed on the circuit member  231 , without forming the circuit patterns having the shape of the second coils  230 . 
     Furthermore, the second coils  230 , which have been prepared by winding wires into a doughnut shape or which have the shape of a finely patterned coil, may be conductively connected to the printed circuit board  250 . 
     The second coils  230  may be disposed over the base  210  and under the housing  140 . The circuit member  231  including the second coils  230  may be disposed on the upper surface of the printed circuit board  250 , which is positioned over the base  210 . 
     However, the disclosure is not limited thereto, and the second coils  230  may be disposed on the base  210  in a state of being in close contact therewith, or may be spaced apart from the base  210  by a predetermined distance. In other examples, a substrate on which the second coils are formed may be layered on the printed circuit board  250  and connected thereto. 
     The printed circuit board  250  may be coupled with the upper surface of the base  210 . As shown in  FIG.  2   , the printed circuit board  250  may have through holes or grooves formed at positions corresponding to the mounting grooves  214  so as to allow the mounting grooves  214  to be exposed therethrough. 
     The printed circuit board  250  may be provided with the terminal members  253 , which are formed by bending portions of the printed circuit board  250  and to which the terminals  251  are attached. The embodiment illustrates the printed circuit board  250  having two bent terminal members  253 . Each terminal member  253  includes a plurality of terminals  251  for the application of external power to the terminal members  253 , whereby current is supplied to the first coil  120  and the second coils  230 . The number of terminals  251  provided on each terminal member  253  may be increased or decreased depending on the kinds of components to be controlled. Alternatively, the number of terminal members  253  provided on the printed circuit board may be one, or three or more. 
     A cover member  300 , which is configured to have an approximate box shape, may accommodate the movable unit, the second coils  230  and a portion of the printed circuit board  250 , and may be coupled with the base  210 . The cover member  300  may serve to protect the movable unit, the second coils  230 , the printed circuit board  250  and the like, accommodated therein, from damage, and may serve to inhibit an electromagnetic field, which is generated by the first magnets  130 , the first coil  120 , the second coils  230  and the like, from leaking outward, thereby concentrating the electromagnetic field. 
       FIG.  3    is a perspective view illustrating the support members  220  according to an embodiment of the present invention.  FIG.  4    is a front view illustrating the support member  220  according to the embodiment. 
     The support member  220  may be coupled at an upper portion thereof to the upper elastic member  150 . The support member  220  may also be coupled at another upper portion thereof to the housing  140 . 
     As illustrated in  FIG.  3   , the support member  220  according to the embodiment may be disposed on a side surface of the housing  140 . The support member  220  may be coupled with the mounting groove  214  formed in the base  210  by means of an adhesive or the like, and may be bonded at an upper side thereof to a side surface of the housing  140  and to the upper elastic member  150 . 
     Since the support members  220  are respectively disposed on the outer surfaces of the cuboidal housing  140 , a total of four support members may be symmetrically disposed so as to surround the bobbin  110 . However, the disclosure is not limited thereto, and a total of eight support members  220  may also be disposed two on each side surface of the housing  140 . 
     The support member may be conductively connected to the upper elastic member  150 , or may be conductively connected to a straight surface of the upper elastic member  150 . Since the support member  220  is prepared separately from the elastic member  150 , the support member  220  may be conductively connected to the upper elastic member  150  by means of a conductive adhesive, solder or the like. 
     As illustrated in  FIG.  4   , the support member  220  may include a first coupling portion  221 , a first elastic deformation portion  222 , a second elastic deformation portion  223 , a second coupling portion  224 , a connecting portion  225  and a first protruding portion  226 . 
     The first coupling portion  221  may be coupled with an upper portion of the housing  140 , and may be provided with through holes  800  formed therethrough. The first coupling portion  221  may be bonded at the region of the through holes  800  to a second protruding portion  149  protruding from the upper surface of the housing  140 . The first coupling portion  221  may also be bonded to the upper elastic member  150 , and detailed description thereof will be given later. 
     As illustrated in  FIG.  4   , at least one through hole  800  may be formed in opposite ends of the first coupling portion  221 . By applying an adhesive to the through holes  800 , the first coupling portion  221  may be bonded to the housing  140 . The structure in which the first coupling portion  221  is coupled with the housing  140  will be described in detail later. 
     In another embodiment, the second coupling portion  224  may be provided with a recess (not shown), and the housing  140  may be provided with a coupling protrusion (not shown). Accordingly, by fitting the coupling protrusion into the recess, the second coupling portion  224  may be coupled with the housing  140 . 
     The second coupling portion  224  may be the portion that is coupled with the base  224 , and may be provided at the lower end of the support member  220 . The second coupling portion  224  may be configured to have a plate shape having a width larger than the width of the first elastic deformation portion  222  and the second elastic deformation portion  223 . However, the disclosure is not limited thereto, and the second coupling portion  224  may have a width smaller than or equal to the width of the first elastic deformation portion  222  and the second elastic deformation portion  223 . 
     According to the embodiment, as illustrated in  FIG.  4   , the second coupling portion  224  may be composed of a pair of coupling portions, which are connected to each other and diametrically opposed and which are respectively fitted or disposed in the mounting grooves  214  in the base  210 . The second coupling portion  224  may be fixedly coupled with the mounting groove  214  formed in the base  210  by means of an adhesive such as epoxy. Alternatively, the second coupling portion  224  may be coupled with the base  210  without the mounting groove  214 . 
     However, the disclosure is not limited thereto, and the second coupling portion  224  may be coupled with the mounting groove  214  merely by fitting the second coupling portion  224  into the mounting groove  214  in an interference fitting manner. The second coupling portion  224  may be a single coupling portion, or may be composed of two or more coupling portions. In this case, the base  210  may be provided with the mounting groove  214  in a number corresponding to the number of second coupling portion  224 . 
     The first elastic deformation portion  222  may be composed of a pair of elastic deformation portions, which extend from the first coupling portion  221  and are diametrically opposed. The second elastic deformation portion  223  may be composed of a pair of elastic deformation portions, which extend from the second coupling portion  224  and are diametrically opposed. 
     Each of the first and second elastic deformation portions  222  and  223  may be configured to have a predetermined pattern, which is prepared by bending the elastic deformation portions at least once. According to the embodiment, the elastic deformation portions may include the first and second elastic deformation portions  222  and  223 . The first elastic deformation portion  222  extends from the first coupling portion  221  so as to be connected to the connecting portion  225 . The second elastic deformation portion  223  extends from the first coupling portion  221  so as to be connected to the connecting portion  225 . 
     The first and second elastic deformation portions may be disposed with the connecting portion  225  interposed therebetween, and may be configured to have shapes corresponding to each other. 
     In an example, when the first elastic deformation portion  222  is configured to have a zigzag shape by bending the elastic deformation portion  222  two times or more as illustrated in  FIG.  4   , the second elastic portion  223  may be configured to have a corresponding zigzag shape. However, the disclosure is not limited thereto, and only the first elastic deformation portion  222  may be provided or the second elastic deformation portion  223  may be configured to have a different shape. 
     The above configuration is merely an example, and the elastic deformation portions may be configured to have various other shapes. The elastic deformation portions may be constructed into a single elastic deformation portion without division into the first and second elastic deformation portions  222  and  223 , and may be configured to have suspension wire shapes without the bent pattern. 
     According to the embodiment, the straight portions of the first and second elastic deformation portions  222  and  223  may be disposed so as to be approximately parallel to a plane perpendicular to the first direction. 
     When the housing  140  is moved in the second and/or third direction along a plane perpendicular to the first direction, the first and second elastic deformation portions  222  and  223  may be elastically deformed to a minute extent in a direction in which the housing  140  moves or in the longitudinal direction of the support member  220 . 
     As a result, the housing  140  is able to move in the second and third directions defining a plane perpendicular to the first direction with almost no displacement in the first direction, thereby improving the accuracy of the handshake correction. The improvement is obtained by employing the ability of the elastic deformation portions  222  and  223  to be extensible in the longitudinal direction. Here, the longitudinal direction may be a direction in which the first coupling portion  221  is connected to the second coupling portion  224 . 
     The connecting portion  225  may be composed of a pair of connecting portions, which connect the first and second elastic deformation portions  222  and  223  to each other and which are disposed to be diametrically opposed to each other. The connecting portion  225  may be disposed between the first and second elastic deformation portions  222  and  223 , as described above. However, the disclosure is not limited thereto, and the connecting portion  225  may be connected to only one of the first and second elastic deformation portions  222  and  223 . 
     In the embodiment, although each of the first and second elastic deformation portions  222  and  223  is composed of a pair of elastic deformation portions, each of the first and second coupling portions  221  and  224  is integrally formed, and is able to couple both the first and second elastic deformation portions  222  and  223  to the housing  140  and the base  210 . 
     Each of opposite ends of the support member  220  may be provided with one or more coupling portions, and one or more elastic deformation portion may be provided between the support members  220 . 
     The first protrusion  226  may protrude downward from the first coupling portion  221 . Although the first protruding portion  226  is illustrated in  FIG.  4    as having a T-shape, the disclosure is not limited thereto. For example, the first protruding portion  226  may be configured to have various shapes, such as a bar shape, a circular shape, an elliptic shape and a curved shape. 
     The first protrusion  226  may be bonded to a lateral side surface of the housing  140  so as to function to fix or couple an upper portion of the support member  220  to a lateral side surface of the housing  140 . Here, if only the first protrusion  226  is bonded to the housing  140  in order to bond the support member  220  to the housing  140 , it is impossible to provide sufficient coupling strength between the support member  220  and the housing  140 . 
     In this case, the support member  220  may be separated from the housing  140  due to the repeated application of external shocks, thereby causing malfunction or breakage of the lens moving apparatus. Hence, there is a problem in that it is impossible to assure the mechanical reliability of the lens moving apparatus. A specific structure of the lens moving apparatus capable of overcoming this problem will be described later. 
       FIG.  5    is a front view illustrating the support member  220  according to the embodiment of the present invention.  FIG.  6    is a partial perspective view illustrating the support member  220  according to the embodiment. 
     The first protruding portion  226  of the support member  220  may be bonded to the lateral side surface of the housing  140 . The lateral side surface of the housing  140  may be provided at a region thereof corresponding to the first protruding portion  226  with a fourth protruding portion  147 , which is to be bonded to the first protruding portion  226 . The fourth protruding portion  147  may protrude in a direction toward the first protruding portion  226 . 
     Accordingly, an adhesive may be applied to the opposing surfaces of the first protruding portion  226  and the fourth protruding portion  147 . As the adhesive is cured, the first protruding portion  226  may be bonded to the fourth protruding portion  147 , whereby the support member  220  is bonded to the housing  140 . 
     The region of the lateral side surface of the housing  140 , at which the support member  220  is disposed, may be formed into an inclined surface  148 . As illustrated in  FIG.  6   , the inclined surface  148  may be configured to have a surface area capable of accommodating the entire support member  220 . 
     The inclined surface  148  may be formed by depressing a portion of the lateral side surface of the housing  140  that corresponds to a surface area capable of accommodating the entire support member  220 . Here, the depressed region of the lateral side surface of the housing  140  may be configured such that the distance between the housing  140  and the support member  220  is increased moving downward. 
     In other words, due to the formation of the inclined surface  148 , the distance between the lateral side surface of the housing  140  and the support member  220  may be increased moving downwards. By virtue of this configuration, when the support member  220  moves along an x-y plane perpendicular to the first direction, interference between the housing  140  and the support member  220  may be remarkably reduced, thereby improving the handshake correction function of the lens moving apparatus. 
       FIG.  7    is an enlarged view illustrating portion A of  FIG.  6   . As described above, the second protruding portion  149  may protrude from the upper surface of the housing  140  in the first direction, and an end of the first coupling portion  221 , in which the through holes  800  are formed, may be bonded to the second protruding portion  149 . Referring to  FIG.  7   , the process of bonding the first coupling portion  221  to the second protruding portion  149  will now be described. 
     First, an adhesive is applied to opposing surfaces of an end of the first coupling portion  221  and the second protruding portion  149 . Subsequently, the end of the first coupling portion  221  is bonded to the second protruding portion  149 , and an adhesive is further applied to the opposite surface  221   b  of the end of the first coupling portion  221 . 
     Thereafter, as the adhesive is cured, the opposing surfaces of the end of the first coupling portion  221  and the second protruding portion  149  may be bonded or coupled with each other by means of the adhesive. At this time, after curing of the adhesive, adhesive trapped in the through holes  800  and adhesive on the opposite surface  221   b  may serve as a fastening element, such as a fixing pin, a rivet or the like. 
     Consequently, by virtue of the bonding structure using an adhesive, the first coupling portion  221  and the second protruding portion  149  may be firmly fixed or coupled with each other. As a result, the support member  220  and the housing  140  may also be firmly coupled with each other. 
     In another embodiment, an adhesive may be applied only to the opposite surface  221   b  of the end of the first coupling portion  221 , which is positioned opposite the opposing surface of the end of the first coupling portion  221 . In this case, since a portion of the adhesive applied to the opposite surface  221   b  infiltrates between the opposing surfaces of the end of the first coupling portion  221  and the second protruding portion  149  through the through holes  800 , the opposing surfaces may be fixed or coupled with each other by the infiltrated adhesive. 
     Accordingly, according to the embodiment, the through holes  800  are formed through the region of the first coupling portion  221  of the support member  220  that is bonded to the housing  140 , and the support member  220  and the housing  140  are adhesively coupled with each other by means of an adhesive. Consequently, there is an effect of being able to increase the coupling strength between the support member  220  and the housing  140 . 
     The first coupling portion  221  may be bonded to the upper elastic member  150 . As illustrated in  FIG.  7   , a bonding portion  900  may be provided in order to bond the first coupling portion  221  and the upper elastic member  150  to each other. 
     The bonding portion  900  may function to couple the first coupling portion  221  and the upper elastic member  150  to each other by being applied or formed between a portion of the first coupling portion  221  and the upper elastic member  150 . 
     In an embodiment, the bonding portion  900  may be applied or formed so as to bond a portion of the opposing surface of the end of the first coupling portion  221  that faces the second protruding portion  149 , the side surface of the second protruding portion  149  and the upper surface of the elastic member, as illustrated in  FIG.  7   . 
     The bonding portion  900  may be applied or formed into a three-dimensional shape, such as a portion of a sphere or an oval sphere. This shape of the bonding portion  900  may be easily realized by using the viscosity and surface tension of the adhesive constituting the bonding portion  900 . 
     The support member  220  and the upper elastic member  150  may be made of a metal material. Meanwhile, the bobbin  110  may be made of a plastic material. 
     Coupling between components made of the same material using an adhesive may remarkably enhance the coupling strength between the components, compared to coupling between components made of different materials using an adhesive. 
     In the embodiment, the support member  220  and the bobbin  110  made of a plastic material are coupled with each other using an adhesive, and the support member  220  and the upper elastic member  150 , both of which are made of a metal material, are coupled with each other using an adhesive. 
     Accordingly, since the support member  220  and the upper elastic member  150 , which are made of the same material, particularly, a metal material, are coupled with each other using an adhesive, the coupling strength of the support member  220  to the lens moving apparatus may be remarkably increased. 
     Consequently, the embodiment may remarkably reduce malfunction or breakage of the lens moving apparatus, which is caused by low coupling strength of the support member  220  and consequent separation of the support member  220  from the housing  140  due to the repeated application of external shocks. As a result, there is an effect of being able to secure the mechanical reliability of the lens moving apparatus. 
       FIG.  8    is a view illustrating another embodiment of portion A of  FIG.  6   . In this embodiment, the upper elastic member  150  may be provided with a third protruding portion  159  at a region thereof facing the lower end of the first coupling portion  221 , as illustrated in  FIG.  8   . 
     In this embodiment, the third protruding portion  159  and the first coupling portion  221  may be bonded to each other in the following manner. First, an adhesive is applied to the opposing surfaces of the end of the first coupling portion  221  and the second protruding portion  149 , or is applied only to the opposite surface of the end of the first coupling portion  221  that is positioned opposite the opposing surface of the end of the first coupling portion  221 . 
     Subsequently, a portion of the adhesive applied to the first coupling portion  221  flows to the third protruding portion  159  and stays there. In the embodiment, the adhesive flowing from the first coupling portion  221  may be trapped between the upper surface  159   a  of the third protruding portion  159  and the lower end  221   a  of the first coupling portion  221 . 
     The adhesive which has flowed from the first coupling portion  221  and has then been trapped between the upper surface  159   a  of the third protruding portion  159  and the lower end  221   a  of the first coupling portion  221  may couple the first coupling portion  221  to the upper elastic member  150 . 
     In the embodiment, the first coupling portion  221  and the first protruding portion  226  may be coupled with each other by means of the adhesive, and, at the same time, the first coupling portion  221  and the third protruding portion  159  may also be coupled with each other by means of the adhesive. In addition, the first coupling portion  221 , the second protruding portion  149  and the upper elastic member  150  may be coupled with one another by means of the bonding portion  150 . 
     In the embodiment, a secure triple bond is established among the support member  220 , the bobbin  110  and the upper elastic member  150 , and the support member  220  is coupled with the lateral side surface of the bobbin  110 . By virtue of this multiple bonding structure, the support member  220  may be firmly coupled with the lens moving apparatus. 
     In the embodiment, the adhesive that is used or the bonding portion  900  may be composed of epoxy or thermosetting bond. However, the disclosure is not limited thereto, and any material may be used as long as the material satisfies coupling strength and other properties required in design of the lens moving apparatus. 
     The lens moving apparatus according to the embodiment may be incorporated in devices in various fields, for example, a camera module. Such a camera module may be applied to mobile devices such as cellular phones. 
     The camera module according to the embodiment may include the lens barrel coupled with the bobbin  110 , an image sensor (not shown), and a printed circuit board. The lens barrel may be configured as described above, and the printed circuit board  250  may define the bottom surface of the camera module from a portion thereof on which the image sensor is mounted. The lens barrel may include at least one lens for transmitting an image to the image sensor. 
     The camera module may further include an infrared- screening filter (not shown). The infrared-screening filter serves to shield the image sensor from light in an infrared range. 
     The base  210  shown in  FIG.  2    may include the infrared-screening filter mounted at a position corresponding to the image sensor, and may be coupled with a holder member (not shown). The holder member may support a lower side of the base  210 . 
     The base  210  may be provided with an additional terminal member for connection with the printed circuit board  250 , and the terminal member may also be integrally formed using a surface electrode. 
     The base  210  may serve as a sensor holder for protecting the image sensor. In this case, although the base  210  may be provided along the lateral side surface thereof with protrusions that project downward, these are not essential components. Although not shown in the drawings, an additional sensor holder disposed under the base  210  may fulfill the same function as the protrusions. 
       FIG.  9    is a schematic perspective view illustrating a lens moving apparatus according to another embodiment.  FIG.  10    is an exploded perspective view illustrating the lens moving apparatus shown in  FIG.  9   . 
     Referring to  FIG.  9   , the lens moving apparatus according to the embodiment may include a first lens moving unit (not shown), a second lens moving unit (not shown) and a cover member  1300 . Here, the first lens moving unit  100  may fulfill the function of the above-described autofocusing device, and the second lens moving unit  200  may fulfill the function of the above-described handshake correction device. 
     The cover member  1300  may be configured to have an approximate box shape, and may surround the first and second lens moving units (not shown). 
     As shown in  FIG.  10   , the lens moving apparatus according to the embodiment may include a movable unit. The movable unit may fulfill the autofocusing and handshake correction functions of the lens. The movable unit may include a bobbin  1110 , a first coil  1120 , first magnets  1130 , a housing  1140 , an upper elastic member  1150  and a lower elastic member  1160 . 
     The bobbin  1110  may be provided on the outer surface thereof with the first coil  1120  disposed between the first magnets  1130 . Due to the electromagnetic interaction between the first magnets  1130  and the first coil  1120 , the bobbin  1110  may reciprocate in the first direction in the space inside the housing  1140 . The bobbin  1110  may be provided on the outer surface thereof with the first coil  1120  so as to electromagnetically interact with the first magnets  1130 . 
     The bobbin  1110  may move in the first direction in the state of being elastically supported by the upper elastic member  1150  and the lower elastic member  1160  in order to fulfill the autofocusing function. 
     The bobbin  1110  may include a lens barrel (not shown) in which at least one lens is mounted. The lens barrel may be coupled with the inside of the bobbin  1110  in various ways. 
     For example, the lens barrel may be coupled with the bobbin  1110  in such a manner as to form a female thread in the inner surface of the bobbin  1110 , form a male thread, corresponding to the female thread, in the outer surface of the lens barrel and threadedly engage the two components with each other. However, the disclosure is not limited thereto, and the lens barrel may be directly held in the bobbin  1110  in ways other than the threaded engagement, without formation of the thread in the inner surface of the bobbin  1110 . Alternatively, the at least one lens may be integrally formed with the bobbin without having to prepare the lens barrel. 
     The lens coupled with the lens barrel may be composed of a single lens or two or more lenses constituting an optical system. 
     The autofocusing function may be controlled by changing the direction of current, or may be fulfilled by the action of moving the bobbin  1110  in the first direction. For example, the bobbin  1110  may be moved upward from its initial position upon the application of forward current, and may be moved downward upon the application of reverse current. The distance by which the bobbin  1110  moves in one direction from the initial position may be increased or decreased by controlling the amount of current flowing in one direction. 
     The bobbin  1110  may be provided on upper and lower surfaces thereof with a plurality of upper support protrusions and a plurality of lower support protrusions, respectively. The upper support protrusions may be configured to have a circular cylindrical shape or a rectangular column shape, and may serve to couple or secure the upper elastic member  1150  thereto. The lower support protrusions may also be configured to have a circular cylindrical shape or a rectangular column shape, and may serve to couple or secure the lower elastic member  1160  thereto, like the upper support protrusions. 
     The upper elastic member  1150  may be disposed on the bobbin, and the lower elastic member  1160  may be disposed under the bobbin  1110 . The upper elastic member  1150  may have through holes corresponding to the upper support protrusions, and the lower elastic member  1160  may have through holes corresponding to the lower support protrusions. The respective support protrusions and the corresponding through holes may be fixedly coupled with each other by means of thermal fusion or an adhesive such as epoxy. 
     The housing  140  may be configured to have a hollow column, for example, an approximately rectangular hollow column capable of supporting the first magnets  1130 . Each lateral side of the housing  1140  may be provided with the first magnet  1130  and support members  1220  secured thereto. 
     As described above, the housing  1140  may be provided therein with the bobbin  1110 , which is moved in the first direction under the guidance of the elastic members  1150  and  1160 . In this embodiment, the first magnets  1130  may be disposed at the corner regions of the housing  1140 , and the support members  1220  may be disposed on the lateral side surfaces of the housing  1140 . 
     The upper elastic member  1150  and the lower elastic member  1160  may elastically support the upward and/or downward movement of the bobbin  1110  in the first direction. The upper elastic member  1150  and the lower elastic member  1160  may be constituted by a leaf spring. 
     As shown in  FIG.  10   , the upper elastic member  1150  may be composed of a pair of elastic members, which are separated from each other. By virtue of this dual partitioning structure, current having different polarities or different electric powers may be applied to the respective partitioned elastic members of the upper elastic member  1150 . In a modification, the lower elastic member  1160  may also be composed of a pair of partitioned elastic members, and the upper elastic member  1150  may be configured to have an integral structure. 
     The upper elastic member  1150 , the lower elastic member  1160 , the bobbin  1110  and the housing  1140  may be assembled to one another by means of thermal fusion and/or bonding using an adhesive or the like. Here, the components may be first coupled with one another by means of thermal fusion, and may then be finally coupled with one another by means of bonding using an adhesive. 
     The base  1210  may be disposed under the bobbin  1110 , and may be configured to have an approximately rectangular shape. A printed circuit board  1250  may be mounted on the base  1210 , and lower portions of the support members  1220  may be coupled with the base  1210 . The base  1210  may be provided in the upper surface thereof with mounting grooves  1214  into which the support members  1220  are fitted. An adhesive may be applied to the mounting grooves  1214  so as to immobilize the support members  1220 . 
     The regions of the base  1210  that face terminal members  1253  of the printed circuit board  1250  may be provided with respective support recesses having a size corresponding to that of the terminal members  1253 . The support recesses may be recessed from the outer circumferential surface of the base  1210  by a predetermined depth such that the terminal members  1253  do not protrude outward from the outer circumferential surface of the base  1210  or such that the extent to which the terminal members  1253  protrude can be controlled. 
     The support members  1220  are disposed on the lateral sides of the housing  1140  such that the upper sides of the support members  1220  are coupled with the housing  1140  and the lower sides of the support members  1220  are coupled with the base  1210 . The support members  1220  may support the bobbin  1110  and the housing  1140  in such a manner as to allow the bobbin  1110  and the housing  1140  to move in the second and third directions, perpendicular to the first direction. The support members  1220  may be conductively connected to the first coil  1120 . 
     Since the support members  1220  according to the embodiment are respectively disposed on the outer surfaces of the cuboidal housing  1140 , a total of four support members may be symmetrically disposed. However, the disclosure is not limited thereto, and a total of eight support members  1220  may alternatively be disposed two on each side surface of the housing  1140 . The support members  1220  may be conductively connected to the upper elastic member  1150 , or may be conductively connected to a straight surface of the upper elastic member  1150 . 
     Since the support member  1220  is prepared separately from the elastic member  1150 , the support member  1220  may be conductively connected to the upper elastic member  1150  by means of a conductive adhesive, solder or the like. Consequently, the upper elastic member  1150  may apply current to the first coil  1120  through the support members conductively connected thereto. 
     Although the support members  1220  are illustrated in  FIG.  10    as being embodied as plate-shaped support members according to an embodiment, the support members  1220  are not limited thereto. In other words, the support members  1220  may be configured to have a wire shape. 
     Second coils  1230  may move the housing  1140  in the second and/or third directions to perform the handshake correction by virtue of electromagnetic interaction with the first magnets  1130 . 
     The second or third direction may include not only the x-axis direction or the y-axis direction but also a direction which is substantially close to the x-axis direction or the y-axis direction. In other words, in terms of driving in the embodiments, although a housing  1140  may move in a direction parallel to the x-axis or the y-axis, the housing may move in a direction which is slightly oblique with respect to the x-axis or the y-axis in the state of being supported by a support member  1220 . 
     The first magnets  1130  are required to be disposed at positions corresponding to the second coils  1230 . 
     The second coils  1230  may be disposed so as to face the first magnets  1130 , which are secured to the housing  1140 . In one embodiment, the second coils  1230  may be disposed outside the first magnets  1130 , or may be disposed under the first magnets  1130  so as to be spaced apart from the first magnets  1130  by a predetermined distance. 
     According to the embodiment, although a total of four second coils  1230  may be disposed one on each corner of a circuit member  1231 , the disclosure is not limited thereto. Only two second coils  1230 , that is, one second coil for movement in the second direction and one second coil for movement in the third direction, may be provided, or a total of more than four second coils  1230  may be provided. 
     In the embodiment, although circuit patterns having the shape of the second coils  1230  are formed on the circuit member  1231  and additional second coils are disposed on the circuit member  1231 , the disclosure is not limited thereto. Alternatively, only additional second coils  1230  may be disposed on the circuit member  1231 , in which case the circuit patterns having the shape of the second coils  1230  are not formed. 
     Furthermore, the second coils  1230 , which have been prepared by winding wires into a doughnut shape or which have the shape of a finely patterned coil, may be conductively connected to the printed circuit board  1250 . 
     The second coils  1230  may be disposed over the base  1210  and under the housing  1140 . The circuit member  1231  including the second coils  1230  may be disposed on the upper surface of the printed circuit board  1250 , which is positioned over the base  1210 . 
     However, the disclosure is not limited thereto, and the second coils  1230  may be disposed on the base  1210  in a state of being in close contact therewith, or may be spaced apart from the base  1210  by a predetermined distance. In other examples, a substrate on which the second coils are formed may be layered on the printed circuit board  1250  and connected thereto. 
     The printed circuit board  1250  may be coupled with the upper surface of the base  1210 . As shown in  FIG.  10   , the printed circuit board  1250  may have through holes or grooves formed at positions corresponding to the mounting grooves  1214  so as to expose the mounting grooves  1214  therethrough. 
     The printed circuit board  1250  may be provided with the terminal members  1253 , which are formed by bending portions of the printed circuit board  1250  and to which the terminals  1251  are attached. The embodiment illustrates the printed circuit board  1250  having two bent terminal members  1253 . Each terminal member  1253  includes a plurality of terminals  1251  for the application of external power to the terminal members  1253 , whereby current is supplied to the first coil  1120  and the second coils  1230 . The number of terminals  1251  provided on each terminal member  1253  may be increased or decreased depending on the kinds of components to be controlled. Alternatively, the number of terminal members  1253  provided on the printed circuit board may be one, or three or more. 
     A cover member  1300 , which is configured to have an approximate box shape, may accommodate the movable unit, the second coils  1230  and a portion of the printed circuit board  1250 , and may be coupled with the base  1210 . The cover member  1300  may serve to protect the movable unit, the second coils  1230 , the printed circuit board  1250  and the like, accommodated therein, from damage, and may serve to inhibit an electromagnetic field, which is generated by the first magnets  1130 , the first coil  1120 , the second coils  1230  and the like, from leaking outward, thereby concentrating the electromagnetic field. 
       FIG.  11    is an exploded perspective view illustrating the base  1210 , the printed circuit board  1250  and the second coils  1230 , according to the embodiment. The lens moving apparatus may further include position sensors  1240 . 
     The position sensors  1240  are disposed at the center of the second coils  1230  so as to detect movement of the housing  1140 . Here, the position sensors  1240  may basically detect movement of the housing  1140  in the first direction. In some cases, the position sensors  1240  may be configured so as to detect movement of the housing  1140  in the second and third directions. 
     The position sensors  1240  may be embodied as hall sensors or the like, but may alternatively be embodied as any sensor as long as the sensor is able to detect variation in magnetic force. As illustrated in  FIG.  11   , a total of two position sensors  1240  may be mounted on the corner regions of the base  1210  disposed under the printed circuit board  1250 . The mounted position sensors  1240  may be received in a position sensor mounting recess  1215  formed in the base  1210 . The lower surface of the printed circuit board  1250  may be the surface opposite the surface on which the second coils  1230  are disposed. 
     The position sensors  1240  may be disposed to be spaced downward apart from the second coils  1230  with the printed circuit board  1250  interposed therebetween. Specifically, the position sensors  1240  are not directly connected to the second coils  1230 . The second coils  1230  may be disposed on the upper surface of the printed circuit board  1250  whereas the position sensors  1240  may be disposed on the lower surface of the printed circuit board  1250 . 
     The lens moving apparatus according to the embodiment may be incorporated in devices in various fields, for example, a camera module. Such a camera module may be applied to mobile devices such as cellular phones. 
     The camera module according to the embodiment may include the lens barrel coupled with the bobbin  1110  and an image sensor (not shown). The lens barrel may include at least one lens for transmitting an image to the image sensor. 
     The camera module may further include an infrared- screening filter (not shown). The infrared-screening filter serves to shield the image sensor from light in an infrared range. 
     The base  1210  shown in  FIG.  10    may include the infrared-screening filter mounted at a position corresponding to the image sensor, and may be coupled with a holder member (not shown). The holder member may support the lower side of the base  1210 . 
     The base  1210  may be provided with an additional terminal member for connection with the printed circuit board  1250 , and the terminal member may also be integrally formed using a surface electrode. 
     The base  1210  may further include an adhesive member  1211  for bonding the printed circuit board  1250  to the base  1210 . 
     The adhesive member  1211  may be provided on one side surface of the base  1210 . The adhesive member  1211  may be disposed at a position at which one side surface of the base  1210  contacts one side surface of the printed circuit board  1250  in a surface-contact manner, as illustrated in the drawing. 
     Although the adhesive member  1211  is illustrated as being disposed on one side surface of the base  1210  in the embodiment, an additional adhesive member  1211  may be further provided on the side surface opposite the side surface on which the base adhesive member  1211  is provided. 
     The adhesive member  1211  shown in the embodiment is merely one embodiment, and any element capable of bonding the printed circuit board  1250  to the base  1210  may be used. The scope of rights of the present invention is not limited as to the position or the number of adhesive members  1211 . 
     The base  1210  may further include an adhesive-member-receiving portion (not shown) which provides a space for accommodating the adhesive member  1211 . 
     The adhesive-member-receiving portion (not shown) is depressed from one surface of the base by a predetermined height so as to provide a space for accommodating the adhesive member  1211 . 
     The adhesive-member-receiving portion (not shown) is required only in order to provide a space for accommodating the adhesive member  1211 , and is not limited to the above embodiment. Furthermore, the adhesive-member-receiving portion does not limit the scope of rights of the present invention. 
     The base  1210  may further include a stepped portion provided in a mounting recess  1214  in which a spring unit (not shown) is disposed. 
     As described above, the adhesive member  1211  may be provided on one surface of the base  1210  in order to bond the printed circuit board  1250  to the base  1210 . Here, if the amount of the adhesive member  1211  is insufficient, the adhesive force between the base  1210  and the printed circuit board  1250  is decreased, thereby causing a phenomenon whereby the printed circuit board  1250  is raised from the base  1210 . Meanwhile, if the amount of the adhesive member  1211  is greater than the correct amount, the adhesive member  1211  flows into the mounting recess, thereby causing a problem in which it is difficult to accurately couple a spring unit (not shown) to the mounting recess  1214 . 
     Hence, the embodiment further includes the stepped portion provided in the mounting recess  1214  of the base  1210  in order to inhibit the adhesive member  1211  from flowing into the mounting recess  1214 . 
     The stepped portion may include at least one side surface portion  12143  defining a side surface of the stepped portion, a lower surface portion  12142  defining the lower surface of the stepped portion and a stepped space  12141  defined by the side surface portion  12143  and the lower surface portion  12142  so as to receive the adhesive member  1211 . 
     The lower surface portion  12142  of the stepped space  12141  may have a linear cross-sectional shape. 
     Alternatively, the lower surface portion  12142  of the stepped space  12141  may have a curved cross-sectional shape that is convex in the first direction. 
     In this case, since the cross-sectional shape of the lower surface portion  12142  of the stepped space  12141  is convex in the first direction perpendicular to the lower surface portion  12142 , the adhesive member  1211  is collected at opposite sides of the lower surface portion  12142 , thereby providing an effect of being able to efficiently inhibit the adhesive member  1211  from flowing into the mounting recess  1214 . 
     Furthermore, the lower surface portion  12142  of the stepped space  12141  may also have a curved cross-sectional shape that is concave in the first direction perpendicular to the lower surface portion  12142 . 
     In this case, since the cross-sectional shape of the lower surface portion  12142  of the stepped space  12141  is concave in the first direction perpendicular to the lower surface portion  12142 , the adhesive member  1211  is collected at the center of the lower surface portion  12142 , thereby providing an effect of being able to efficiently inhibit flow of the adhesive member  1211  into the mounting recess  1214 . 
     In addition, the lower surface portion  12142  of the stepped space  12141  may also have a sine curve shape. 
     In this case, since the cross-sectional shape of the lower surface portion  12142  of the stepped space  12141  is concave at multiple points in the first direction perpendicular to the lower surface portion  12142 , the adhesive member  1211  is collected in multiple recesses of the lower surface portion  12142 , thereby providing an effect of being able to efficiently inhibit the flow of the adhesive member  1211  into the mounting recess  1214 . 
     Although the stepped portion is illustrated as being composed of a single stepped portion in the embodiment, the stepped portion may include a plurality of stepped portions. 
     By the provision of the plurality of stepped portions, the size of a space capable of accommodating the adhesive member  1211  is at least doubled or tripled. Consequently, there is an effect of being able to efficiently inhibit the adhesive member  1211  from flowing into the mounting recess  1214 . 
     The lower surface portion  12142  may further include a plurality of protrusions  12144 . 
     The plurality of protrusions  12144  may protrude upward from the lower surface portion  12142  by a predetermined height. 
     Since the provision of the plurality of protrusions  12144  to the lower surface portion  12142  increases resistance to the flow of the adhesive member  1211  introduced into the stepped portion, it is possible to efficiently inhibit the adhesive member  1211  introduced into the stepped portion from flowing into the mounting recess  1214 . 
     Although the plurality of protrusions  12144  are illustrated in the drawing as having a hemisphere shape, the illustration is merely one embodiment, and the protrusions  12144  may be formed into a conical shape or a polygonal column. 
     The base  1210  may serve as a sensor holder for protecting the image sensor. In this case, although the base  1210  may be provided along the lateral side surface thereof with protrusions that project downward, these are not essential components. Although not shown in the drawings, an additional sensor holder disposed under the base  210  may fulfill the same function as the protrusions. 
     Referring to  FIG.  14   , the second coils  1230  may include fifth through holes  1230   a  that are formed through the corner portions of the circuit member  1231 . The support members  1220  may be connected to the printed circuit board  1250  through the fifth through holes  1230   a.  When the second coils  1230  are finely patterned (FP) coils, optical image stabilizer (OIS) coils  1232  may be formed or disposed on some portions of the finely patterned coils. In addition, the fifth through holes  1230   a  may not be formed in the second coils  1230 , and the support members  1220  may be conductively soldered to the points of the second coils  1230  at which the fifth through holes  1230   a  would otherwise be formed.
