Claim 18:
19. An inductor component comprising:
a main body part including a magnetic layer containing a resin and a metal magnetic powder contained in the resin;
an inductor wiring disposed in the main body part;
an external terminal exposed from the main body part, an outer surface of the external terminal including a concave part; and
a lead-out wiring electrically connecting the inductor wiring and the external terminal, a width of the lead-out wiring is greater than a width of the concave part, wherein
the external terminal includes an overlapping portion located on the lead-out wiring and a non-overlapping portion located on the magnetic layer,
outermost locations of the outer surface of the external terminal between the concave part and an end of the external terminal have a first plane in common and the concave part extends along a second plane offset from the first plane,
the concave part is located on an outer surface of the overlapping portion, and
an arithmetic average roughness of the outer surface of the overlapping portion is smaller than an arithmetic average roughness of an outer surface of the non-overlapping portion.
