Abstract: An inductor component includes a base body, an underlying insulation layer, an inductor wiring line, and a covering insulation layer. The underlying insulation layer is within the base body, and includes a first major face. The inductor wiring line is on the first major face within the base body, and extends along the first major face. The covering insulation layer is within the base body, and covers at least part of the inductor wiring line. The inductor wiring line includes a seed layer, and a plating layer in contact with the seed layer. As seen in a first cross-section orthogonal to a direction in which the inductor wiring line extends: the inductor wiring line includes first and second leg portions and a crotch portion. The first and second leg portions are in opposite end portions of a lower face of the inductor wiring line in a width direction.

Abstract: An inductor component includes an element body, a coil disposed in the element body, and a non-magnetic insulating layer configured to cover at least part of the coil. The element body has a first magnetic layer and a second magnetic layer stacked in order along a first direction. The coil has an inductor wiring extending along a plane orthogonal to the first direction between the first magnetic layer and the second magnetic layer. In a first section orthogonal to an extending direction of the inductor wiring, the inductor wiring has a top surface facing the first direction, a bottom surface facing a second direction as a reverse direction of the first direction, a first side surface facing a third direction orthogonal to the first direction, and a second side surface facing a fourth direction as a reverse direction of the third direction.
