Abstract
First, a melt of Al or a melt of an Al alloy containing Si is injected in a die filled with SiC powder and cast to form a plate member made of an Al/SiC composite. Next, an Al foil member made of an Al—Mg-based alloy is joined with the surface of the plate member through hot pressing. As a result, part of the Al foil member enters casting blowholes on the surface of the plate member to fill the casting blowholes. In addition, an Al—Mg-based alloy layer is formed on the surface of the plate member. Thus, a base plate having a nearly flat surface is produced.
