Beschreibung
Zusammenfassung:	A semiconductor device includes an electric conduction portion having a flat plate shape, a semiconductor element being arranged vertically over the electric conduction portion and being electrically connected thereto, a casing whose lower portion of an inner wall has a coupling portion coupled with a circumferential edge portion of the electric conduction portion and whose upper portion of the inner wall surrounds the whole circumference of the electric conduction portion and a sealing material that vertically downwardly encapsulates the semiconductor element and the electric conduction portion. The electric conduction portion and the casing are integrally molded, and a space having a shape coupled to a circumferential edge portion of the electric conduction portion is provided in the lower portion of the inner wall of the casing as the coupling portion.
