主权项 1. A semiconductor device comprising: a base; a semiconductor element disposed on the base; a wiring pattern formed on a front surface of the base, and made of conductive material; a resist layer formed on the front surface of the base, and covering at least a portion of the wiring pattern; a resin-sealed portion covering the semiconductor element and the resist layer; and a plurality of concave portions formed through first portions of the resist layer, different from second portions of the resist layer covering the at least the portion of the wiring pattern, exposing the front surface of the base from the resist layer, and each of the plurality of concave portions filled with a part of the resin-sealed portion to strongly engage the resist layer and the resin-sealed portion.
