Abstract
A semiconductor device comprises at least a semiconductor module including a semiconductor chip, a heat sink thermally connected to the semiconductor chip and a seal member for covering and sealing the semiconductor chip and the heat sink in such a manner as to expose the heat radiation surface of the heat sink. The radiation surface is cooled by a refrigerant. An opening is formed in a part of the seal member as a refrigerant path through which the refrigerant flows.
