Abstract
An electric power semiconductor device includes a power module and a heat dissipating member connected to the power module through a heat-conductive insulating resin sheet in which a mold resin part included in the power module has a protruding part in its peripheral part to prevent the heat-conductive insulating resin sheet from expanding in a planar direction. The heat-conductive insulating resin sheet is slightly thicker than the protruding part and has a resin exuding part exuded from a small gap between the protruding part and the heat dissipating member while the power module and the heat dissipating member are heated and pressurized to be bonded.
