Abstract
An encapsulated semiconductor device includes: a first conduction path formative plate; a second conduction path formative plate joined to the first conduction path formative plate; a power element bonded to the first conduction path formative plate; a heatsink held by the first conduction path formative plate with an insulation sheet interposed between the heatsink and the first conduction path formative plate; and an encapsulation resin configured to encapsulate the first and second conduction path formative plates. A through hole or a lead gap is formed in a region of the first conduction path formative plate in contact with the insulation sheet. The insulation sheet is press-fitted into the through hole or the lead gap.
