Abstract
Abstract A power semiconductor module comprises a metal base, plural wiring substrates provided on said the base, a first wiring substrate of the wiring substrates having a power circuit portion including a power semiconductor device, and a substrate containing portions having a resin portion in which one of the wiring substrstes is contained. The one of the wiring substrates is positioned in self-alignment on the metal substrate on the basis of an inner wall of the resin portion of the substrate containing portion.
