Summary of the Invention

Problems to be Solved by the Invention

[0004] Here, it has been demanded to improve the performance of an electronic component having a plurality of capacitor portions connected in series inside the body.

[0005] The present invention has been made to solve such problems, and an object thereof is to provide an electronic component having a plurality of capacitor portions connected in series that can improve performance.

Means for Solving the Problems

[0006] The electronic component according to the present invention comprises a body having a first main surface and a second main surface facing a first direction, a first end surface and a second end surface facing a second direction perpendicular to the first direction, and a first side surface and a second side surface facing a third direction perpendicular to the first and second directions; a first internal electrode provided inside the body and drawn out to the first main surface which is the mounting surface; a second internal electrode provided inside the body and provided at a position different from the first internal electrode when viewed from the third direction and drawn out to the first main surface; and a second internal electrode formed on the first main surface and connected to the first internal electrode. The capacitor comprises a terminal electrode, a second terminal electrode formed on a first end face and connected to a second internal electrode, a third internal electrode provided within the body and positioned opposite the first and second internal electrodes in a third direction and extending to a first main surface, and a first external conductor formed on the first main surface and connected to the third internal electrode, wherein the first capacitor section is formed when the first and third internal electrodes face each other in a third direction, and the second capacitor section is formed when the second and third internal electrodes face each other in a third direction.

[0007] In this electronic component, the first capacitor section and the second capacitor section are connected in series via at least a third internal electrode. By connecting multiple capacitor sections in series in this way, short-circuit defects can be reduced. The third internal electrode is connected to the first external conductor. Therefore, by connecting the terminal electrode and the external conductor and performing an inspection and measurement, it is possible to check for the presence or absence of short-circuit defects in the first and second capacitor sections. Furthermore, since the internal electrodes are stacked in a third direction perpendicular to the mounting surface, and the terminal electrodes are formed on the first main surface of the mounting surface, the ESL can be reduced. In addition, since there is no variation due to the stacking position of the internal electrodes, the ESR on the high-frequency side can be stabilized. As a result, the performance of an electronic component having multiple capacitor sections connected in series can be improved.

[0008] The electronic component may have a plurality of first external conductors, and the first and second terminal electrodes may be arranged between the plurality of first external conductors. In this case, the distance between the first and second terminal electrodes can be shortened, thereby reducing the deflection stress between the terminal electrodes when mounting the electronic component.

[0009] The electronic component comprises a plurality of first external conductors, which may be arranged between a first terminal electrode and a second terminal electrode. In this case, mounting the external conductors during the electronic component mounting process can improve the flexural bonding strength between the terminal electrodes.

[0010] At least one of the first internal electrode, the second internal electrode, and the third internal electrode may have a notch at the outer corner in the second direction on the first main surface side. In this case, even if a crack occurs near the corner of the base body, the crack can be avoided by the notch, thereby preventing the crack from reaching the overlapping portion of the internal electrodes that form the capacitor.

[0011] At least one of the first terminal electrode, the second terminal electrode, and the first outer conductor may be positioned at the corner between the first main surface and the end face of the base body. In this case, the starting point of a crack can be kept away from the overlapping portion of the internal electrodes, so that even if a crack occurs near the corner of the base body, it is possible to suppress the crack from reaching the overlapping portion of the internal electrodes.

[0012] The electronic component may further include a first main surface formed thereon, a first terminal electrode, a second terminal electrode, and a second outer conductor positioned outward in a second direction from the first outer conductor. In this case, mounting the second outer conductor during the mounting of the electronic component can improve the deflection fixing strength between the terminal electrodes.

[0013] The electronic component comprises a pair of third internal electrodes, a pair of first external conductors connected to the pair of third internal electrodes, and a fourth internal electrode provided within the component and positioned differently from the first and second internal electrodes when viewed from a third direction. The first capacitor section is formed when the first internal electrode and one of the third internal electrodes face each other in the third direction, the second capacitor section is formed when the second internal electrode and the other third internal electrode face each other in the third direction, the third capacitor section is formed when the fourth internal electrode and one of the third internal electrodes face each other in the third direction, and the fourth capacitor section is formed when the fourth internal electrode and the other third internal electrode face each other in the third direction. In this case, the four capacitor sections can be connected in series via the third and fourth internal electrodes.

[0014] The electronic component may include a third external conductor connected to a fourth internal electrode. In this case, the third external conductor can be used to check for short-circuit defects in the third and fourth capacitor sections.

[0015] The third outer conductor may be formed on the first main surface. In this case, mounting the third outer conductor during the mounting of electronic components can improve mounting strength.

[0016] The third outer conductor may be formed on the second main surface. In this case, a large distance can be secured between the terminal electrodes and the outer conductor formed on the first main surface. [Effects of the Invention]

Mode for Carrying Out the Invention

[0019] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the description, the same reference numerals will be used for the same elements or elements having the same function, and redundant descriptions will be omitted.

[0020] First, referring to Figs. 1 to 3, the configuration of the electronic component 100 according to the present embodiment will be described. Fig. 1 is a front view of the electronic component according to the present embodiment. Fig. 2(a) is a cross-sectional view taken along the line IIa-IIa shown in Fig. 1, and Fig. 2(b) is a cross-sectional view taken along the line IIb-IIb shown in Fig. 1. Fig. 3(a) is a diagram showing the first internal electrode and the second internal electrode, Fig. 3(b) is a diagram showing the third internal electrode, and Fig. 3(c) is a diagram showing the state in which the first internal electrode, the second internal electrode, and the third internal electrode overlap. In Fig. 3(c), the first internal electrode and the second internal electrode are shown by virtual lines.

[0021] In the following explanation, an XYZ coordinate system may be set for the electronic component 100. The Z-axis direction (first direction) is perpendicular to the stacking direction in which the internal electrodes, described later, are stacked. The Z-axis direction is perpendicular to the surface of the circuit board on which the component is mounted during installation. The X-axis direction (second direction) is perpendicular to the Z-axis direction and parallel to the surface of the circuit board during installation. The X-axis direction also corresponds to the longitudinal direction in which the component 2 extends. The Y-axis direction (third direction) is perpendicular to the Z-axis and X-axis directions and parallel to the surface of the circuit board during installation, and perpendicular to the X-axis direction. The Y-axis direction is the direction in which the internal electrodes, described later, are stacked. In Figure 1, the upper side is the positive side of the Z-axis direction, and the lower side is the negative side of the Z-axis direction.

[0022] As shown in Figure 1, the electronic component 100 comprises a base body 2, a first terminal electrode 3, a second terminal electrode 4, and a pair of external conductors 6A and 6B. As shown in Figure 2, the electronic component 100 includes a first internal electrode 11, a second internal electrode 12, and a third internal electrode 13 within the base body 2.

[0023] As shown in Figure 1, the base body 2 is a rectangular parallelepiped component extending along the longitudinal direction, the X-axis. The base body 2 has a first main surface 2a and a second main surface 2b facing each other in the Z-axis direction, a first end surface 2c and a second end surface 2d facing each other in the X-axis direction, and a first side surface 2e and a second side surface 2f facing each other in the Y-axis direction. The first main surface 2a is located on the negative side in the Z-axis direction, and the second main surface 2b is located on the positive side in the Z-axis direction. The first end surface 2c is located on the negative side in the X-axis direction, and the second end surface 2d is located on the positive side in the X-axis direction. The first side surface 2e is located on the negative side in the Y-axis direction, and the second side surface 2f is located on the positive side in the Y-axis direction. Of these, the first main surface 2a becomes the mounting surface that faces the mounting substrate during mounting.

[0024] The shape of base body 2 is not particularly limited, but here it has a rectangular prism shape in which the dimension in the X-axis direction is greater than the dimensions in the Z-axis and Y-axis directions. The rectangular prism shape includes a rectangular prism shape in which the corners and edges are chamfered, and a rectangular prism shape in which the corners and edges are rounded. For example, the length of base body 2 in the X-axis direction may be 1.45 to 3.50 mm, the length in the Y-axis direction may be 0.7 to 1.85 mm, and the length in the Z-axis direction may be 0.7 to 1.85 mm.

[0025] In the prototype 2, multiple dielectric layers (dielectric layers 5 shown in Figure 2) are stacked in the Y-axis direction. Each dielectric layer is made of a sintered ceramic green sheet containing a dielectric material (such as a dielectric ceramic like BaTiO3, Ba(Ti,Zr)O3, or (Ba,Ca)TiO3). In the actual prototype 2, each dielectric layer 5 is integrated to such an extent that the boundaries between each dielectric layer 5 are not visible.

[0026] Terminal electrodes 3 and 4 are provided on the first main surface 2a of the base body 2. Terminal electrodes 3 and 4 are parts that electrically connect other members to the electronic component 100 and function as effective terminals. Terminal electrodes 3 and 4 are formed at predetermined positions in the X-axis direction on the first main surface 2a and extend in the Y-axis direction (see Figure 2(a)). External conductors 6A and 6B are provided on the first main surface 2a of the base body 2. The first external conductors 6A and 6B improve the fixing strength with other members and function as terminals for measuring electrical characteristics. The first external terminals 6A and 6B are formed at predetermined positions in the X-axis direction on the first main surface 2a and extend in the Y-axis direction. In this embodiment, the first external terminal 6A, the first terminal electrode, the second terminal electrode, and the first external terminal electrode 6B are provided in order from the negative side to the positive side in the X-axis direction. As a result, the first terminal electrode 3 and the second terminal electrode 4 are positioned between the multiple first external conductors 6A and 6B.

[0027] As shown in Figure 2, the internal electrodes 11, 12, and 13 are flat, plate-shaped conductor patterns extending parallel to the XZ plane. Multiple internal electrodes 11, 12, and 13 are formed in the Y-axis direction. The first internal electrode 11 is provided in the negative region in the X-axis direction within the base body 2 and is connected to the first terminal electrode 3 on the first main surface 2a. The second internal electrode 12 is provided in the positive region in the X-axis direction within the base body 2 and is connected to the second terminal electrode 4 on the first main surface 2a. The second internal electrode 12 is provided at a different position from the first internal electrode 11 when viewed from the Y-axis direction. The first internal electrode 11 and the second internal electrode 12 are arranged in the same plane. That is, the first internal electrode 11 and the second internal electrode 12 are formed on the same dielectric layer 5 and have the same position in the Y-axis direction. In the state before lamination, the conductor patterns of the first internal electrode 11 and the second internal electrode 12 are formed on the ceramic green sheet of the dielectric layer 5.

[0028] The third internal electrode 13 is provided in both the negative and positive regions in the X-axis direction within the base body 2 and is drawn out to the first main surface 2a. The third internal electrode 13 is positioned on a different plane from the internal electrodes 11 and 12. That is, the third internal electrode 13 is formed on a different dielectric layer 5 than the internal electrodes 11 and 12, and its position in the Z-axis direction is different. In the state before lamination, the conductor pattern of the third internal electrode 13 is formed on the ceramic green sheet of the dielectric layer 5.

[0029] Referring to Figure 3, an example of the specific shape of each internal electrode 11, 12, and 13 will be described. In the following description, the center line CL in the X-axis direction set with respect to the base body 2 may be used for explanation. As shown in Figure 3(a), the first internal electrode 11 and the second internal electrode 12 are symmetrical with respect to the center line CL. The first internal electrode 11 is formed in the region on the negative side of the X-axis direction from the center line CL. The first internal electrode 11 comprises a main body portion 21 and an extension portion 22. The main body portion 21 has a rectangular outer shape. The four edges of the main body portion 21 are arranged to be spaced apart from the first main surface 2a, the second main surface 2b, the first end surface 2c, and the center line CL. The extension portion 22 extends from the inner (positive side) end of the main body portion 21 in the X-axis direction to the negative side in the Z-axis direction and is exposed on the first main surface 2a, thereby connecting to the first terminal electrode 3.

[0030] The second internal electrode 12 is formed in a region on the positive side of the X-axis direction relative to the center line CL. The second internal electrode 12 comprises a main body portion 23 and an extension portion 24. The main body portion 23 has a rectangular outer shape. The four edges of the main body portion 23 are spaced apart from the first main surface 2a, the second main surface 2b, the second end surface 2d, and the center line CL. The extension portion 24 extends from the inner (negative side) end of the main body portion 23 in the X-axis direction to the negative side in the Z-axis direction and is exposed on the first main surface 2a, thereby connecting to the second terminal electrode 4. A gap is formed between the first internal electrode 11 and the second internal electrode 12 at a position including the center line CL.

[0031] As shown in Figure 3(b), the third internal electrode 13 has a symmetrical configuration with respect to the center line CL. The third internal electrode 13 comprises a main body portion 26 and a pair of lead-out portions 27A and 27B. The main body portion 26 extends both to the negative and positive sides in the X-axis direction with respect to the center line CL. When viewed from the Z-axis direction, the main body portion 26 has an external shape similar to the main body portion 21 of the first internal electrode 11 on the negative side in the X-axis direction, and an external shape similar to the main body portion 23 of the second internal electrode 12 on the positive side in the X-axis direction, and has a shape that connects the portion corresponding to the main body portion 21 and the portion corresponding to the main body portion 23 (see Figure 3(c)). Furthermore, the main body portion 26 is positioned to face both the main body portions 21 and 23 in the Z-axis direction. The lead-out portion 27A extends from the outer (negative side) end of the main body portion 26 in the X-axis direction to the negative side in the Z-axis direction and is exposed on the first main surface 2a, thereby connecting to the external conductor 6A. The lead-out portion 27B extends from the outer (positive) end in the X-axis direction of the main body portion 26 to the negative side in the Z-axis direction and is exposed on the first main surface 2a, thereby connecting to the external conductor 6B.

[0032] As described above, as shown in Figure 2(b), a first capacitor section 10A is formed inside the base body 2 in the negative region in the X-axis direction, and a second capacitor section 10B is formed in the positive region in the X-axis direction. The first capacitor section 10A is composed of a first internal electrode 11 and a third internal electrode facing each other in the Y-axis direction. The first capacitor section 10A is formed by alternately stacking a plurality of first internal electrodes 11 and a plurality of third internal electrodes 13. The second capacitor section 10B is formed by alternately stacking a plurality of second internal electrodes 12 and a plurality of third internal electrodes 13. The first capacitor section 10A and the second capacitor section 10B are connected in series by the main body 26 of the third internal electrode.

[0033] As shown in Figure 2, the first internal electrode 11 and the second internal electrode 12 are positioned in the outermost layer of the stacked internal electrodes. That is, among the internal electrodes arranged inside the base body 2, the first internal electrode 11 and the second internal electrode 12 are positioned furthest to the positive side in the Y-axis direction, and the first internal electrode 11 and the second internal electrode 12 are positioned furthest to the negative side in the Y-axis direction.

[0034] Next, the operation and effects of the electronic component 100 according to this embodiment will be described.

[0035] In the electronic component 100, the first capacitor section 10A and the second capacitor section 10B are connected in series via at least a third internal electrode 13. In this case, even if one of the capacitor sections 10A and 10B is damaged, the capacitor function of the other remains, thus reducing short-circuit failures. By connecting multiple capacitor sections 10A and 10B in series in this way, short-circuit failures can be reduced. Furthermore, the third internal electrode 13 is connected to the first external conductors 6A and 6B. Therefore, by connecting the terminal electrodes 3 and 4 to the external conductors 6A and 6B and performing an inspection and measurement, it is possible to check for the presence or absence of short-circuit failures in the first capacitor section 10A and the second capacitor section 10B.

[0036] Here, with reference to Figure 4, the electronic component 200 of the comparative example will be described. In the electronic component 200 of the comparative example, internal electrodes are stacked in the Z-axis direction perpendicular to the mounting surface, and terminal electrodes 203 and 204 are formed on the end faces 2c and 2d perpendicular to the mounting surface. When the electronic component 200 is mounted on the substrate with the first main surface 2a as the mounting surface, the current path L1 passing through the negative internal electrode in the Z-axis direction, which is the stacking direction, and the current path L2 passing through the positive internal electrode do not form equivalent circuits, resulting in an unstable high-frequency ESR for the electronic component 200. Furthermore, when the terminal electrode 203 is connected to the electrode PD on the substrate side via the solder portion BD, the solder portion BD extends to a high position in the Z-axis direction, which increases the crack CR generated by the bending stress, potentially reaching the overlapping portion of the internal electrodes 11 and 13 in the capacitor portion 10A.

[0037] In contrast, in the electronic component 100 according to this embodiment, the internal electrodes are stacked in the Y-axis direction perpendicular to the mounting surface, and terminal electrodes 3 and 4 are formed on the first main surface 2a, which is the mounting surface, so that the ESL can be reduced. Furthermore, since there is no variation due to the stacking position of the internal electrodes, the ESR on the high-frequency side can be stabilized. As a result, the performance of the electronic component 100 having multiple capacitor sections 10A and 10B connected in series can be improved.

[0038] Furthermore, since the terminal electrodes 3 and 4 are formed on the first main surface 2a, which is the mounting surface, when connecting the first terminal electrode 3 to the substrate electrode PD via the solder portion BD, it is not necessary to raise the solder portion BD significantly in the Z-axis direction. Therefore, it is possible to avoid the crack CR reaching the overlapping portion of the internal electrodes 11 and 13 (see Figure 2(a)). Also, in the comparative example, the electronic component 200 has terminal electrodes 203 and 204 formed on the end faces 2c and 2d, so the mounting area increases due to the larger dimension in the X-axis direction. On the other hand, in the electronic component 100 of this embodiment, the mounting area can be reduced because the terminal electrodes 3 and 4 are formed on the mounting surface.

[0039] The electronic component 100 comprises a plurality of first external conductors 6A and 6B, and the first terminal electrode 3 and the second terminal electrode 4 are arranged between the plurality of first external conductors 6A and 6B. In this case, the distance between the first terminal electrode 3 and the second terminal electrode 4 can be shortened, so that the deflection stress between the terminal electrodes 3 and 4 can be reduced when the electronic component 100 is mounted. For example, in the electronic component 200 according to the comparative example shown in Figure 4, the terminal electrodes 3 and 4 are formed at both ends in the X-axis direction, so the distance between them is large. Therefore, the stress when deflection occurs between the terminal electrodes 3 and 4 is large.

[0040] The present invention is not limited to the embodiments described above.

[0041] The structure of the internal electrodes of the electronic component 100 is not limited to the embodiments described above. For example, the structure shown in Figure 5 may be adopted. The electronic component 100 shown in Figure 5 comprises a plurality of first external conductors 6A, 6B, and the plurality of first external conductors 6A, 6B may be arranged between the first terminal electrode 3 and the second terminal electrode 4. In this case, when mounting the electronic component 100, mounting the first external conductors 6A, 6B as well can improve the deflection fixing strength between the terminal electrodes 3 and 4.

[0042] Specifically, as shown in Figure 5(a), the first terminal electrode 3, the first outer conductor 6A, the first outer conductor 6B, and the second terminal electrode 4 are provided in order from the negative side to the positive side in the X-axis direction. The lead-out portion 22 of the first internal electrode 11 is provided at the negative end in the X-axis direction of the main body 21. The lead-out portion 24 of the second internal electrode 12 is provided at the positive end in the X-axis direction of the main body 23. Also, as shown in Figure 5(b), lead-out portions 6A and 6B are provided near the center line CL of the third internal electrode 13.

[0043] Furthermore, as shown in Figure 6(a), the main body portion 21 of the first internal electrode 11 may have a notch 31A at the outer (negative) corner in the X-axis direction on the first main surface 2a side, and the main body portion 23 of the second internal electrode 12 may have a notch 31B at the outer (positive) corner in the X-axis direction on the first main surface 2a side. In this case, even if a crack occurs near the corners CR1 and CR2 of the base body 2, the crack can be avoided by the notches 31A and 31B, thereby preventing the crack from reaching the overlapping portion of the internal electrodes that form the capacitor portions 10A and 10B. Note that the notch configuration shown in Figure 6(a) may also be applied to the configuration in Figure 5. In this case, the corner of the main body portion 26 of the third internal electrode 13 on the first main surface 2a side has a notch.

[0044] Furthermore, as shown in Figure 6(b), the first external conductors 6A and 6B may be positioned at the corners CR1 and CR2 between the first main surface 2a and the end faces 2c and 2d of the base body 2. In this case, the first external conductors 6A and 6B, which are the starting points of cracks, can be kept away from the overlapping portion of the internal electrodes. Therefore, even if a crack occurs near the corners CR1 and CR2 of the base body 2, it is possible to suppress the crack from reaching the overlapping portion of the internal electrodes. In this case, the lead-out portions 27A and 27B of the third internal electrode 13 extend inclined toward the corners CR1 and CR2. Note that the configuration shown in Figure 6(b) may also be applied to the configuration in Figure 5. In this case, the first terminal electrode 3 and the second terminal electrode 4 are positioned at the corners CR1 and CR2, and the lead-out portions 22 and 24 extend inclined toward the corners CR1 and CR2.

[0045] For example, the structure shown in Figure 7 may be adopted. As shown in Figure 7, the electronic component 100 comprises a pair of third internal electrodes 13A, 13B, a pair of first external conductors 6A, 6B connected to the pair of third internal electrodes 13A, 13B, and a fourth internal electrode 14 provided within the body 2 and positioned differently from the first internal electrode 11 and the second internal electrode 12 when viewed from the Y-axis direction. As shown in Figure 7(c), the first capacitor section 10A is formed when the first internal electrode 11 and one of the third internal electrodes 13A face each other in the Y-axis direction, the second capacitor section 10B is formed when the second internal electrode 12 and the other third internal electrode 13B face each other in the Y-axis direction, the third capacitor section 10C is formed when the fourth internal electrode 14 and one of the third internal electrodes 13A face each other in the Y-axis direction, and the fourth capacitor section 10D is formed when the fourth internal electrode 14 and the other third internal electrode 13 face each other in the Y-axis direction. In this case, the four capacitor sections 10A, 10C, 10D, and 10B can be connected in series via the third internal electrodes 13A, 13B and the fourth internal electrode 14.

[0046] As shown in Figure 7(a), the fourth internal electrode 14 is positioned further apart in the positive Z-axis direction than the first internal electrode 11 and the second internal electrode 12. The fourth internal electrode 14 has a rectangular body portion 28 and a lead portion 29. The body portion 28 is formed to extend in both the positive and negative regions in the X-axis direction with respect to the center line CL. The lead portion 29 is led out from the body portion 28 in the positive Z-axis direction and is exposed on the second main surface 2b. The lead portion 29 is connected to the third external conductor 7 formed on the second main surface 2b.

[0047] As shown in Figure 7(b), the pair of third internal electrodes 13A and 13B are formed by dividing one internal electrode 13 shown in Figure 3(b) at the position of the center line CL. One of the third internal electrodes 13A is formed in the negative region in the X-axis direction relative to the center line CL. The main body 26A of one of the third internal electrodes 13A faces the first internal electrode 11 in the negative region in the Z-axis direction and faces the fourth internal electrode 14 in the positive region in the Z-axis direction. The other third internal electrode 13B is formed in the positive region in the X-axis direction relative to the center line CL. The main body 26B of the other third internal electrode 13B faces the second internal electrode 12 in the negative region in the Z-axis direction and faces the fourth internal electrode 14 in the positive region in the Z-axis direction.

[0048] As described above, the electronic component 100 may include a third external conductor 7 connected to the fourth internal electrode 14. In this case, the third external conductor 7 can be used to check for short-circuit defects in the third capacitor section 10C and the fourth capacitor section 10D.

[0049] The third outer conductor 7 may be formed on the second main surface 2b. In this case, the distance between the terminal electrodes 3 and 4 and the outer conductors 6A and 6B formed on the first main surface 2a can be increased.

[0050] Alternatively, the configuration shown in Figure 8 may be adopted instead of Figure 7. As shown in Figure 8(a), the fourth internal electrode 14 of the electronic component 100 is positioned between the first internal electrode 11 and the second internal electrode 12 in the X-axis direction. The lead portion 29 of the fourth internal electrode 14 extends from the main body 28 toward the negative side in the Z-axis direction. The first terminal electrode 3, the first external conductor 6A, the second external conductor 7, the first external conductor 6B, and the second terminal electrode 4 are formed on the first main surface 2a in order from the negative side toward the positive side in the X-axis direction. The fourth internal electrode 14 is connected to the second external conductor 7 on the first main surface 2a side.

[0051] As shown in Figure 8(c), one third internal electrode 13A forms a first capacitor section 10A by facing the first internal electrode 11 near its negative edge in the X-axis direction. The other third internal electrode 13A forms a third capacitor section 10C by facing the fourth internal electrode 14 near its positive edge in the X-axis direction. The other third internal electrode 13B forms a fourth capacitor section 10D by facing the fourth internal electrode 14 near its negative edge in the X-axis direction. The other third internal electrode 13B forms a second capacitor section 10B by facing the second internal electrode 12 near its positive edge in the X-axis direction.

[0052] The third outer conductor 7 may be formed on the first main surface 2a. In this case, mounting the third outer conductor 7 when mounting the electronic component 100 can improve mounting strength.

[0053] The configuration shown in Figure 9 may also be adopted. As shown in Figure 9(a), the electronic component 100 may further include second external conductors 8A and 8B formed on the first main surface 2a and positioned outside in the X-axis direction of the first terminal electrode 3, second terminal electrode 4, and first external conductors 6A and 6B. In this case, the deflection fixing strength between the terminal electrodes 3 and 4 can be improved by mounting the second external conductors 8A and 8B when mounting the electronic component 100.

[0054] Specifically, on the first main surface 2a, the second external conductor 8A, the first terminal electrode 3, the first external conductor 6A, the first external conductor 6B, the second terminal electrode 4, and the second external conductor 8B are formed in order from the negative side to the positive side in the X-axis direction. Inside the base body 2, fifth internal electrodes 15A and 15B are formed at the positions of the second external conductors 8A and 8B and are connected to the second external conductors 8A and 8B.

[0055] Furthermore, the first internal electrode 11 and the second internal electrode 12 may have notches 32A and 32B at the outer corners in the X-axis direction on the first main surface 2a side. Also, as shown in Figure 9(b), the third internal electrode 13 may have notches 33A and 33B at the outer corners in the X-axis direction on the first main surface 2a side. In this case, even if a crack occurs near the corner of the base body 2, the crack can be avoided by the notches 32A, 32B, 33A, and 33B, thereby preventing the crack from reaching the overlapping portion of the internal electrodes that form the capacitor portions 10A and 10B (see Figure 9(c)).
