[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-60747 Summary of the Invention [Problem to be solved by the invention]

[0004] In electronic components with multiple filters, even when a shield is placed between the filters to ensure isolation, magnetic flux may leak between the filters, which may cause inductor coupling between the filters, resulting in losses and degrading the performance of the electronic component.

[0005] An object of one aspect of the present invention is to provide an electronic component that can achieve improved characteristics. [Means for solving the problem]

[0006] (1) An electronic component according to one aspect of the present invention comprises a base body formed by stacking a plurality of insulator layers; a first conductor group including a first inductor constituting a first filter having a first passband; a second conductor group including a second inductor constituting a second filter having a second passband; a first shield arranged between the first inductor and the second inductor when viewed from the stacking direction of the plurality of insulator layers and extending in another direction perpendicular to the one direction in which the first conductor group and the second conductor group are aligned; and a second shield extending in the one direction, wherein the second shield is arranged in an area outside the first conductor group when viewed from the stacking direction.

[0007] An electronic component according to one aspect of the present invention includes a first shield and a second shield. The first shield is disposed between the first inductor and the second inductor and extends in the other direction. This ensures isolation between the first inductor (first filter) and the second inductor (second filter) in the electronic component. Furthermore, the second shield extends in one direction and is disposed in an area outside the first conductor group when viewed from the stacking direction. This allows the second shield to suppress the intrusion of magnetic flux between the first inductor and the second inductor in the electronic component. Therefore, the electronic component can improve isolation between the first filter and the second filter. As a result, the electronic component can achieve improved characteristics.

[0008] (2) In the electronic component of (1), the first shield and the second shield may be connected to each other. This configuration further improves the isolation between the first filter and the second filter.

[0009] (3) In the electronic component of (1) or (2), the axial direction of the first inductor and the axial direction of the second inductor may intersect when viewed from the stacking direction. In this configuration, magnetic flux may flow between the first inductor and the second inductor. Therefore, in a configuration in which the axial direction of the first inductor and the axial direction of the second inductor intersect, providing a second shield is particularly effective in improving isolation.

[0010] (4) In the electronic component of (3), the axial direction of the second inductor may intersect with the extending direction of the first shield when viewed from the stacking direction. This configuration improves isolation between the first filter and the second filter.

[0011] (5) In the electronic component of (4), the axial direction of the first inductor may intersect with the extending direction of the second shield when viewed from the stacking direction. This configuration improves isolation between the first filter and the second filter.

[0012] (6) In the electronic component of any one of (1) to (5) above, the second shield may extend along the outer surface of the element body, which can effectively prevent magnetic flux from wandering around.

[0013] (7) In the electronic component of any one of (1) to (6), the second shield may overlap at least a portion of the first inductor or the second inductor when viewed from another direction. This configuration can effectively suppress magnetic flux from leaking in.

[0014] (8) In any one of the electronic components described above in (1) to (7), the heights of the first shield and the second shield in the stacking direction may be the same as the height of the first inductor in the stacking direction. This configuration further improves isolation between the first filter and the second filter.

[0015] (9) An electronic component according to one aspect of the present invention comprises a base body formed by stacking a plurality of insulator layers, a first conductor group including a first inductor constituting a first filter having a first passband, a second conductor group including a second inductor constituting a second filter having a second passband, and a shield extending in one direction in which the first conductor group and the second conductor group are aligned when viewed from the stacking direction of the plurality of insulator layers.

[0016] An electronic component according to one aspect of the present invention includes a shield extending in one direction in which the first conductor group and the second conductor group are aligned when viewed from the stacking direction. This allows the shield to suppress the magnetic flux from leaking between the first inductor and the second inductor. Therefore, the electronic component can improve isolation between the first filter and the second filter. As a result, the electronic component can achieve improved characteristics.

[0017] (10) In the electronic component of (9), the first inductor and the second inductor may each be positioned near one side surface of the element body, and the shield may be positioned between the first inductor and the one side surface. This configuration can effectively suppress magnetic flux leakage.

[0018] (11) In the electronic component of (9) or (10), the axial direction of the first inductor and the axial direction of the second inductor may intersect. In this configuration, magnetic flux may flow between the first inductor and the second inductor. Therefore, in a configuration in which the axial direction of the first inductor and the axial direction of the second inductor intersect, providing a shield is particularly effective in improving isolation.

[0019] (12) In the electronic component of (11), the axial direction of the first inductor may intersect with the extending direction of the shield. This configuration improves isolation between the first filter and the second filter.

[0020] (13) In the electronic component of any one of (9) to (12), the shield may overlap at least a portion of the first inductor or the second inductor when viewed from a direction perpendicular to the direction in which the first conductor group and the second conductor group are arranged. This configuration effectively prevents magnetic flux from leaking in.

[0021] (14) In the electronic component of any one of (9) to (13), the shield may be disposed across the region where the first conductor group is disposed and the region where the second conductor group is disposed. This configuration can effectively suppress the intrusion of magnetic flux. [Effects of the Invention]

Hereinafter, the facing direction of the end faces 2a and 2b is referred to as a first direction (one direction) D1, the facing direction of the main faces 2c and 2d is referred to as a second direction D2, and the facing direction of the side faces 2e and 2f is referred to as a third direction (other direction) D3. The first direction D1, the second direction D2, and the third direction D3 are substantially perpendicular to each other.

[0027] The end faces 2a, 2b extend in the second direction D2 to connect the principal faces 2c, 2d. The end faces 2a, 2b also extend in the third direction D3 to connect the side faces 2e, 2f.
