To provide a semiconductor device which acquires conductivity between a connection terminal and a ground probe even when the connection terminal is coated with a coating material having electrical resistivity higher than that of a basis material.
A semiconductor device comprises: a semiconductor element; connection terminals 26, 28 coated with a coating material having electrical resistivity higher than that of a basis material and connected with the semiconductor element and connected with an external member by welding; a coating material removal part 38 in which the coating material is partially removed and which is formed on a part contacting the connection terminals 26, 28 with a ground probe 46 so as to contact the ground probe with the basis material of the connection terminals 26, 28, the ground probe flowing weld current I occurring when the connection terminals 26, 28 are welded to a ground side.
