Abstract
A base plate has a mounting surface on which a semiconductor element is mounted and a heat-radiation surface for radiating heat to a cooler. The cover has a portion that seals the semiconductor element on the mounting surface of the base plate. The cover has a projecting portion arranged outside the heat-radiation surface and projecting from a level of the heat-radiation surface in a thickness direction. The intermediate layer is arranged on the heat-radiation surface of the base plate, projects from the level of the projecting portion of the cover in a thickness direction, and is made of a thermoplastic material in a solid-phase state.
