Patent ID: 10325711

Abstract:
A coil component: including a first planar spiral wiring and a second planar spiral wiring located above the first planar spiral wiring in a laminated direction and interconnected through connection vias to the first planar spiral wiring. The second planar spiral wiring is wound in a direction different from a winding direction of the first planar spiral wiring when viewed in the laminated direction. The first planar spiral wiring and the second planar spiral wiring have respective innermost circumferential overlapping portions overlapping with each other at the innermost circumferential region when viewed in the laminated direction. At least both end parts of the innermost circumferential overlapping portion of the first planar spiral wiring are in an interconnection with at least both end parts of the innermost circumferential overlapping portion of the second planar spiral wiring through the connection vias.
