Heavy-current flowing circuit substrate, a method for producing the heavy-current flowing circuit substrate, and an assembled unit of a heavy-current flowing circuit substrate and a printed circuit substrate

摘要

A heavy-current flowing circuit substrate 1 comprises a resin-molded body 2 in which a plurality of bus bars 4 made of an elongated metallic plate 3 are embedded and both ends of each of the bus bars 4 are projected from the resin-molded body 2 so as to use them as connecting terminals, the heavy-current flowing circuit substrate 1 being attached or formed integrally with at least one printed circuit substrate 12 mounting thereon electronic devices 13.
