Abstract
An inductor component including a magnetic layer in which a magnetic metal powder is dispersedly present in a base material made of an insulation material and an inductor wiring line laminated on a surface of the magnetic layer. The inductor wiring line includes an anchor portion extending from a main face of the inductor wiring line on a side of the magnetic layer and covering a surface of the magnetic metal powder in the magnetic layer.

A inductor component, comprising:
- a magnetic layer in which a magnetic metal powder is dispersedly present in a base material made of an insulation material;
- and
- an inductor wiring line laminated on a surface of the magnetic layer, the inductor wiring line including an anchor portion extending from a main face of the inductor wiring line on a side of the magnetic layer and covering a surface of the magnetic metal powder in the magnetic layer.
A manufacturing method of an inductor component, comprising:
- covering, by a resist layer, part of a surface of a first magnetic layer in which a magnetic metal powder is dispersed in a base material made of an insulation material and part of the magnetic metal powder is exposed to the surface;
- laminating an inductor wiring line in a portion of the surface of the first magnetic layer that is absent of the resist layer by immersing the first magnetic layer after the covering in a plating solution, the inductor wiring line being also on a surface of the magnetic metal powder exposed to the surface of the first magnetic layer;
- and
- removing, after the laminating, the resist layer.
