A semiconductor device includes a substrate, a conductive part formed on a front surface of the substrate, a semiconductor chip disposed on the front surface of the substrate, a control unit that controls the semiconductor chip, a sealing resin that covers the semiconductor chip, the control unit and the conductive part, and a first lead bonded to the conductive part and partially exposed from the sealing resin. The conductive part includes a first pad and a second pad disposed apart from each other. The first lead is bonded to the first pad and the second pad.
