Abstract
A power semiconductor module includes: a plurality of semiconductor element substrates disposed on the same plane, each of which includes an insulating substrate with a front-side electrode formed on one of the surfaces of an insulator plate and a back-side electrode formed on the other surface of the insulator plate and a power semiconductor element fixed on a surface of the front-side electrode; and a wiring member that electrically connects with each other the semiconductor element substrates adjacent to each other; and the semiconductor element substrates and the wiring member are molded with mold resin; wherein the mold resin is provided with a recessed part, between the insulating substrates adjacent to each other, which is not filled with the resin constituting the mold resin to a predetermined depth from the side of the back-side electrode.
