Abstract
An inductor component comprising a first magnetic layer, a spiral wiring disposed on the first magnetic layer, and a second magnetic layer covering the spiral wiring. The first magnetic layer and the second magnetic layer contain a magnetic powder and a resin containing the magnetic powder, and the spiral wiring includes a spiral-shaped first conductor layer and a second conductor layer disposed on the first conductor layer and shaped along the first conductor layer.
Claims20
An inductor component comprising:
- a first magnetic layer;
- a spiral wiring disposed on the first magnetic layer;
- and
- a second magnetic layer covering the spiral wiring, wherein
- the first magnetic layer and the second magnetic layer contain a magnetic powder and a resin containing the magnetic powder,
- the spiral wiring includes a spiral-shaped first conductor layer and a second conductor layer disposed on the first conductor layer and shaped along the first conductor layer, and
- a density of the magnetic powder is different between a first portion of the second magnetic layer in contact with a side surface of the first conductor layer and a second portion of the second magnetic layer in contact with a side surface of the second conductor layer.
