Abstract:
A common-mode choke coil includes a multilayer body, a first coil, and a second coil. The multilayer body includes plural stacked non-conductor layers. The first and second coils are incorporated in the multilayer body. The first coil includes a first coil conductor. The second coil includes a second coil conductor disposed along an interface between non-conductor layers different from an interface between non-conductor layers along which the first coil conductor is disposed. With the first coil conductor and the second coil conductor being viewed in plan in the stacking direction of the multilayer body, the first coil conductor and the second coil conductor have no portion where the two coil conductors overlap each other, except for a portion where the two coil conductors cross each other.
