Coil component

Abstract

A coil component is capable of reducing specific resistance of a coil and reliably mitigating stress. A coil component includes a base body and a coil disposed in the base body. The base body includes a plurality of magnetic layers laminated in a first direction. The coil includes a plurality of coil wires laminated in the first direction. The coil wires extend along a plane orthogonal to the first direction. Each of the coil wires includes a first coil conductor layer and a second coil conductor layer laminated in the first direction. Specific resistance of the first coil conductor layer is smaller than specific resistance of the second coil conductor layer. Also, in a section orthogonal to an extending direction of each of the coil wires, the second coil conductor layer is adjacent to one side of the first coil conductor layer in the first direction, and a cavity portion is disposed in at least a part between the first coil conductor layer and one of the magnetic layers adjacent to another side of the first coil conductor layer in the first direction.
