Claim:
1. A semiconductor device comprising: a first substrate on which a semiconductor element is mounted; a heat-dissipating plate; an insulating layer disposed between the first substrate and the heat-dissipating plate; and molding resin that molds the first substrate, the heat-dissipating plate, and the insulating layer, the heat-dissipating plate having a first surface opposite to the insulating layer, the first surface being exposed from the molding resin, the insulating layer having at least two curved areas that are curved to the first surface and at least two ends that are located in the molding resin, the heat-dissipating plate being rectangular, the two curved areas of the insulating layer facing two predetermined sides of four sides of the heat-dissipating plate and the insulating layer over-hangs two predetermined sides of four sides of the heat-dissipating plate.
