A positive side conductor (3) and a negative side conductor (2) of an input terminal electrically connected to semiconductor elements, are electrically insulated from each other, and are laminated with each other, and the input terminal having such a laminated structure, an output terminal (4) and substrates (15a-f) mounted thereon the semiconductor elements are arranged in a checkered pattern in a container (1). Further, the semiconductor elements mounted on the substrates (15a-f), the input terminal and the output terminal (4) are electrically connected to one another so as to obtain a loop-like electric path on a conductive member, thereby it is possible to aim at miniaturizing the power conversion apparatus and lowering the inductance thereof.
