[0003] [Patent Document 1] Special Publication No. 2016-508356 Summary of the Invention [Problem to be solved by the invention]

[0004] An object of one aspect of the present invention is to provide an electronic component that can effectively utilize the space within its body and can obtain desired characteristics. [Means for solving the problem]

[0005] (1) An electronic component according to one aspect of the present invention comprises a base body and a plurality of inductors disposed within the base body, the plurality of inductors including a first inductor, a second inductor and a third inductor, each of which has two conductors extending in one direction and a connecting conductor connecting one end of each of the two conductors in the one direction, and the axial directions of each of the first inductor, second inductor and third inductor are parallel to each other and do not overlap with each other when viewed from the one direction.

[0006] In an electronic component according to an aspect of the present invention, the axial directions of the first inductor, the second inductor, and the third inductor are parallel and do not overlap each other when viewed from one direction. In this manner, in the electronic component, the inductors can be efficiently arranged by arranging the multiple inductors with offset axes within the element body. Therefore, the electronic component can effectively utilize the space within the element body (the space efficiency within the element body can be improved). In addition, in the electronic component, the multiple inductors include at least the first inductor, the second inductor, and the third inductor. In this configuration, the inductance of the inductors can be adjusted by making the axial directions of the inductors parallel and do not overlap each other when viewed from one direction. Therefore, the electronic component can obtain desired characteristics.

[0007] (2) In the electronic device of (1) above, the directions of the magnetic fields generated in the first inductor and the second inductor and the magnetic field generated in the third inductor may be opposite to each other. In this configuration, it is possible to prevent the elements including the first inductor and the second inductor and the elements including the third inductor from affecting each other's characteristics.

[0008] (3) In the electronic component of (1) or (2) above, in the first inductor, a first opening is formed by the two conductors and the connecting conductor, in the second inductor, a second opening is formed by the two conductors and the connecting conductor, in the third inductor, a third opening is formed by the two conductors and the connecting conductor, and the first opening and the second opening at least partially overlap when viewed from the axial direction, and the first opening and the third opening do not necessarily overlap. With this configuration, inductance can be suitably adjusted.

[0009] (4) In the electronic component of (1) or (2) above, in the first inductor, the first opening is formed by the two conductors and the connecting conductor, in the second inductor, the second opening is formed by the two conductors and the connecting conductor, and in the third inductor, the third opening is formed by the two conductors and the connecting conductor, and the first opening is smaller than the second opening, and at least a part of the first opening and the second opening overlap when viewed from the axial direction, and the first opening and the third opening do not have to overlap. In a case where an element including the first inductor and the second inductor and an element including the third inductor have different characteristics, if the first opening of the first inductor is smaller than the second opening of the second inductor, the first inductor may be more affected by the third inductor than the second inductor. Therefore, by preventing the first opening and the third opening from overlapping, the first inductor can be suppressed from being affected by the third inductor. As a result, in the electronic component, it is possible to adjust the inductance, etc., and obtain desired characteristics.

[0010] (5) In the electronic component of any one of (1) to (4), each of the multiple inductors may have two conductors extending in one direction and a connecting conductor connecting one end of each of the two conductors in the one direction. With this configuration, it is possible to control the magnetic field of the inductor and to efficiently arrange the inductor.

[0011] (6) In the electronic component of any one of (1) to (5) above, the first inductor, the second inductor, and the third inductor may be arranged side by side in the axial direction. With this configuration, the inductors can be arranged efficiently within the element body. Also, magnetic coupling between the first inductor, the second inductor, and the third inductor can be suppressed.

[0012] (7) In any one of the electronic components described in (1) to (5), the multiple inductors include a fourth inductor and a fifth inductor, each of which has two conductors extending in one direction and a connecting conductor connecting one end of each of the two conductors in the one direction, and the axial directions of the fourth inductor and the fifth inductor are parallel and do not overlap each other when viewed from the one direction, and the axial directions of the first inductor, the second inductor, and the third inductor may be perpendicular to the axial directions of the fourth inductor and the fifth inductor when viewed from the one direction. In this configuration, the multiple inductors can be arranged efficiently by arranging the multiple inductors with their axes shifted in the element body. Therefore, the electronic component can effectively utilize the space in the element body (the spatial efficiency in the element body can be improved). In addition, in the electronic component, the multiple inductors include a fourth inductor and a fifth inductor. In this configuration, the inductance of the inductors can be adjusted by making the axial directions of the inductors parallel and do not overlap each other when viewed from the one direction. Therefore, the electronic component can obtain desired characteristics. Effect of the Invention

[0013] According to one aspect of the present invention, it is possible to effectively utilize the space within the element body and obtain desired characteristics. [Brief description of the drawings]

As shown in Figures 2(a), 2(b) and 3, the electronic component 1 includes an element body 2, a first terminal electrode 3, a second terminal electrode 4 and a third terminal electrode 5. In Figure 3, the element body 2 is indicated by a two-dot chain line.

[0020] The element body 2 has a rectangular parallelepiped shape. The rectangular parallelepiped shape includes a rectangular parallelepiped shape with chamfered corners and ridges, and a rectangular parallelepiped shape with rounded corners and ridges. The element body 2 has, as outer surfaces, a pair of end faces 2a, 2b, a pair of main faces 2c, 2d, and a pair of side faces 2e, 2f. The end faces 2a, 2b face each other.

[0077] 6, the opening A2 of the inductor section 11 is smaller than the opening A3 of the inductor section 12 and the opening A4 of the inductor section 30. The opening A3 of the inductor section 12 may be smaller than the opening A4 of the inductor section 30, may be the same as the opening A4 of the inductor section 30, or may be larger than the opening A4 of the inductor section 30.

[0078] When viewed from the first direction D1, the opening A2 of the inductor section 11 overlaps with the opening A3 of the inductor section 12.

[0079] As described above, in the electronic component 1 according to this embodiment, the directions of the respective axial centers AX2, AX3, and AX4 of the inductor portion 11, the inductor portion 12, and the inductor portion 30 are parallel and do not overlap with each other when viewed from the second direction D2. In this manner, in the electronic component 1, the inductors can be efficiently arranged by arranging the multiple inductors in the element body 2 with the axial centers AX2, AX3, and AX4 offset from each other. Therefore, in the electronic component 1, the space in the element body 2 can be effectively utilized (the space efficiency in the element body 2 can be improved). In addition, in the electronic component 1, the multiple inductors include the inductor portion 11, the inductor portion 12, and the inductor portion 30. In this configuration, the directions of the respective axial centers AX2, AX3, and AX4 are parallel and do not overlap with each other when viewed from the second direction D2, so that the inductances of the inductor portion 11, the inductor portion 12, and the inductor portion 30 can be adjusted. Therefore, the electronic component 1 can obtain desired characteristics.

[0080] In the electronic component 1 according to this embodiment, the direction of the magnetic field generated in each of the inductor portions 11 and 12 is opposite to that of the magnetic field generated in the inductor portion 30. With this configuration, it is possible to prevent the first filter F1 (element) including the inductor portion 11 and the inductor portion 12 and the second filter F2 including the inductor portion 30 from affecting each other's filter characteristics.

[0081] In the electronic component 1 according to this embodiment, in the inductor section 11, an opening A2 is formed by the first conductor 11A, the second conductor 11B, and the first inductor conductor 11C, in the inductor section 12, an opening A3 is formed by the first conductor 12A, the second conductor 12B, and the first inductor conductor 12C, and in the inductor section 30, an opening A4 is formed by the first conductor 30A, the second conductor 30B, and the first inductor conductor 30C. In the electronic component 1, when viewed from the first direction D1 (axial direction), the opening A2 and the opening A3 overlap, and the opening A2 and the opening A4 do not overlap. With this configuration, inductance can be suitably adjusted.

[0082] In the electronic component 1 according to this embodiment, the opening A2 of the inductor portion 11 is smaller than the opening A3 of the inductor portion 12. In the electronic component 1, the opening A2 and the opening A3 overlap when viewed from the first direction D1, and the opening A2 and the opening A5 do not overlap. In a case where the first filter F1 including the inductor portion 11 and the inductor portion 12 and the second filter F2 including the inductor portion 30 have different characteristics, if the opening A2 of the inductor portion 11 is smaller than the opening A3 of the inductor portion 12, the inductor portion 11 may be more affected by the inductor portion 30 than the inductor portion 12. Therefore, by preventing the opening A2 and the opening A4 from overlapping, the inductor portion 11 can be suppressed from being affected by the inductor portion 30. As a result, in the electronic component 1, it is possible to adjust the inductance and obtain the desired characteristics.

[0083] In electronic component 1 according to this embodiment, inductor portion 11, inductor portion 12, and inductor portion 30 are arranged side by side in the direction of axes AX2, AX3, and AX4. With this configuration, the inductors can be arranged efficiently within element body 2. Furthermore, magnetic coupling between inductor portion 11, inductor portion 12, and inductor portion 30 can be suppressed.

[0084] In electronic component 1 according to this embodiment, the directions of the respective axial centers AX1 and AX5 of inductor portion 10 and inductor portion 31 do not overlap with each other and are parallel to each other when viewed from second direction D2. In electronic component 1, the directions of the respective axial centers AX2, AX3, and AX4 of inductor portion 11, inductor portion 12, and inductor portion 30 are perpendicular to the respective axial centers AX1 and AX5 of inductor portion 10 and inductor portion 31 when viewed from second direction D2. In this configuration, by arranging multiple inductors with their axial centers shifted within element body 2, the inductors can be arranged efficiently. Therefore, in electronic component 1, the space within element body 2 can be effectively utilized (space efficiency within the element body can be improved).

However, it is sufficient that electronic component 1 includes at least inductor portion 10, inductor portion 11, and inductor portion 12.
