Abstract
An electric power converter includes a switching device that performs electric-power conversion through switching, an insulated substrate having a first side and a second side that are opposite to each other, a first circuit with which the switching device is electrically connected and that is bonded to the first side of the insulated substrate, a second circuit that is formed in a shape the same as that of the first circuit and is bonded to the second side of the insulated substrate, and a base to which the second circuit is bonded through the intermediary of a bonding layer; each of corner portions in the respective planar shapes of the first circuit and the second circuit has a stress relaxation portion that is formed in such a way as to have a smaller thickness than the other portion.
