Abstract
The respective main electrodes of the semiconductor switching elements such as IGBTs, which are respectively mounted on the plurality of insulating boards, are electrically connected to each other via the conductor member. This configuration makes it possible to suppress the occurrence of the resonant voltage due to the junction capacity and the parasitic inductance of each semiconductor switching element.
