Abstract:
1. A power semiconductor module comprising: a common unit having: a ceramic substrate provided with a circuit surface and a radiation surface opposed to said circuit surface, the circuit surface is disposed with a semiconductor element, a first electrode terminal extending toward a side opposite to said radiation surface, and a package formed by resin molding processing with heat resistant resin to seal said circuit surface and a part of said first electrode terminal, and to expose said radiation surface; and a module casing having: a radiator fitting surface which a radiator is fitted onto, a unit abutting contact part that is in abutting contact with said common unit, whereby said common unit is sandwiched between said unit abutting contact part and said radiator, and an opening that exposes the radiation surface of said common unit on said radiator fitting surface; wherein said package has a step part, the step part opens toward a side opposite to said radiation surface; and said first electrode terminal is formed to be extruded parallel to said ceramic substrate from said package at a valley line of the step part, and to be bent in a outer side of said package toward the side opposite to said radiation surface.
