Abstract
A semiconductor devicehas a metallic base substratefor heat-dissipating, a wiring board, a MOSFETas a semiconductor element, externally leading terminalsA,B,C, a casingformed of a synthetic resin, a fixing resin, and a gel-like resin layer. On the metallic base substrate, the casingis disposed to surround one ends of the externally leading terminalsA,B,C and the MOSFET. The other ends of the externally leading terminalsA,B,C are externally protruded from the casing, and terminal body portionsA,B,C for coupling them are inserted in through hole portionsA,B,of the casing. The terminal body portionsA,B,C and the through hole portionsA,B,are fixed with the fixing resin, and the gel-like resin layeris formed at the lower part of the casing. A spaceis formed between the gel-like resin layerand the casing
