Abstract
A reliable semiconductor module and a reliable power conversion device using the semiconductor module are obtained. A semiconductor module includes a heat dissipation member, a semiconductor device, and a thermally conductive insulating resin sheet. The thermally conductive insulating resin sheet connects the heat dissipation member and the semiconductor device. The semiconductor device includes a semiconductor element and a metal wiring member. The metal wiring member is electrically connected to the semiconductor element. The metal wiring member includes a terminal portion protruding outside the semiconductor device. In a surface portion of the semiconductor device, a concave portion is formed outward of a partial region to which the thermally conductive insulating resin sheet is connected. The concave portion is located in a region closer to the heat dissipation member than the terminal portion.
