Abstract
In order to bring a moduled power converter into less size and cost in the case of a structure having a lead-insert-case, an insulated metal circuit board and a printed circuit board, a difficulty was encountered in thinning a wiring width and an increase in pad area for each metal wire has interfered with a reduction in its size and cost. In the present invention to cope with it, a power converter is constructed by using a semiconductor module having such a structure that a metal base and lead frames are adhered to each other in a state in which an insulating adhesive sheet is interposed therebetween, a resin-molded outer package is adhered to the metal base with an adhesive or the like, and a resin sealing agent is charged into the resin-molded outer package to thereby integrally seal the resin-molded outer package and circuit parts such as semiconductor elements implemented therein, whereby a reduction in size and cost thereof is realized.
