Inductor component

An inductor component comprising:

• a base body;
• an underlying insulation layer within the base body and including a first major face;
• an inductor wiring line on the first major face within the base body, the inductor wiring line extending along the first major face;
• and
• a covering insulation layer within the base body, the covering insulation layer covering at least part of the inductor wiring line,
• wherein
• the inductor wiring line includes a seed layer, and a plating layer disposed 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
• a first leg portion and a second leg portion that are in opposite end portions of a lower face of the inductor wiring line in a width direction, the lower face being a face near the first major face, the width direction being a direction parallel to the first major face, the first leg portion and the second leg portion being embedded in the underlying insulation layer, and
• a crotch portion between the first leg portion and the second leg portion,
• the underlying insulation layer includes a projection, the projection being located between the first leg portion and the second leg portion and facing the crotch portion, and
• at least part of the seed layer is at the crotch portion and in contact with an upper face of the projection.
