Claim:
1. A semiconductor device comprising: a semiconductor element having an upper surface and a lower surface; a metal plate thermally connected to the lower surface; an upper surface electrode soldered to the upper surface; an insulating sheet formed on the upper surface electrode so as to be in surface contact with the upper surface electrode; a shielding plate formed on the insulating sheet so as to be in surface contact with the insulating sheet, the shielding plate shielding against radiation noise; and a resin with which the semiconductor element is covered, while a portion of the upper surface electrode, a lateral portion of the shielding plate and a lower surface of the metal plate are exposed to the outside of the semiconductor device, wherein the heat conductivity of the insulating sheet is higher than the heat conductivity of the resin.
