Abstract: PROBLEM TO BE SOLVED: To improve heat conduction property by putting a bored prepreg in a position of a projection formed in a metallic plate, arranging a metallic foil in an outside thereof, charging a clearance hole with resin under heating pressurizing, pouring resin into a recessed part of a metallic projection part, and thermally setting it. SOLUTION: A conic trapezoid projection (e) is formed in both sides of a metallic plate (d) and a clearance hole is bored. A prepreg or a resin sheet wherein a hole which is a little larger than an area of the conic trapezoid projection (e) is bored in both sides is put and a metallic foil (i) is arranged in the both sides and lamination molding is carried out under heating, pressurizing and preferably under vacuum. According to this constitution, a tip part of the conic trapezoid projection (e) is in firm contact with the metallic film (i) in front and rear sides.  As a result, heat generated from a semiconductor chip (h) is transferred to the metallic plate (d) through the conic trapezoid projection (e) by heat conduction, conducted to a solder ball pad through the conic trapezoid projection (e) at the opposite side and diffused to a mother board printed wiring board, thus improving heat conduction property.
