1. A power conversion device comprising:
a semiconductor device;
insulating substrates, each connected to either the surfaces of said semiconductor device;
thermal-conductive members, each connected to the opposite side of each said insulating substrate with respect to said semiconductor device, said semiconductor device, insulating substrate and thermal-conductive member forming laminated structure section;
a positive-pole semiconductor module and a negative-pole semiconductor module, each with one of said thermal-conductive members being connected to the other end thereof across the laminated structure section formed by said semiconductor device and said insulating substrates;
input/output wiring electrically connected to said semiconductor device; and
a heat-releasing structure releasing the heat transmitted to said thermal-conductive members to the outside.
