Abstract
A semiconductor module includes an upper arm and a lower arm of an inverter circuit. The upper arm has a switching element and a rectifying device and the lower arm has a switching element and a rectifying device. The upper arm and the lower arm are laminated such that the switching elements overlap each other and the rectifying devices overlap each other. Refrigerant flow paths constituting cooling sections respectively extend along both sides in the lamination direction of the switching elements and the rectifying devices and are folded back at the rectifying device lamination section side.
