Abstract: A composite material has SiC produced by preliminarily sintering a porous body having a coefficient of thermal expansion lower than the coefficient of thermal expansion of copper to construct a network therein, the SiC being impregnated with a copper alloy. The copper alloy comprises copper and one or more additive elements which are prepared to impart a coefficient of thermal conductivity of 160 W/mK or higher to the composite material. The additive elements comprise up to 5% of at least one element selected from Be, Al, Si, Mg, Ti, Ni, Bi, Te, Zn, Pb, Sn, and mish metal, and also contains unavoidable impurities and gas components.

Abstract: A mass of graphite is placed into a case, and the case is put into a furnace (step S301). The space in the furnace is heated to produce a porous sintered body of graphite (step S302). Thereafter, the case with the porous sintered body contained therein is removed from the furnace, and put into a cavity in a press (step S303). Then, a molten mass of a metal is poured into the case (step S304), and a punch is inserted into the cavity to press the molten metal into the porous sintered body in the case (step S305).
