Title: POWER CONVERSION DEVICE
Abstract:
A power conversion device (1) has a metal substrate (15) disposed on an aluminum case (23) with an insulation sheet (25) interposed therebetween. In the metal substrate (15), a circuit pattern (21) is disposed on an aluminum base (17) with an insulation layer (19) interposed therebetween. A semiconductor element (3) is mounted to the circuit pattern (21). The metal substrate (15) is fixed to the aluminum case (23) by screws (27) and insulation bushings (29). The insulation sheet (25), which has insulating properties, is sandwiched between the metal substrate (15) and the aluminum case (23) by tightening the screws (27).
