Abstract
A semiconductor apparatus, including an insulated substrate having a first surface and a second surface that are opposite to each other, a semiconductor element that is mounted on the first surface of the insulated substrate, and a cooler for cooling the semiconductor element. The cooler includes a heat dissipation board having a bonding surface and a heat dissipation surface that are opposite to each other, the bonding surface being bonded to the second surface of the insulated substrate, a plurality of fins provided on the heat dissipation surface of the heat dissipation board, and a cooling case having a recess accommodating the plurality of fins, an inner wall surface of the cooling case being in the recess. The heat dissipation surface is provided with a plurality of engagement pieces that position the cooling case by engaging portions of the inner wall surface of the cooling case.
