Abstract

A chip 12 having an electric circuit and a plurality of leads 8 connected electrically with the chip 12 are molded in a resin-sealed package 46 by a molding material containing a main component of a resin, by introducing a molding compound sheet 20 into the cavities 33 of molds 31, 32 before the molds are clamped, by melting the molding compound sheet 20 in the cavities 33 into a liquid molding material 45 after the mold clamping action to pressure fill up the inside of the cavities 33, and by setting the liquid molding material 45 integrally.
