PROBLEM TO BE SOLVED: To provide an Al-SiC composite material which has a thermal expansion coefficient close to that of a ceramic substrate, has improved thermal conductivity and strength, and is prevented from warping. SOLUTION: This Al-SiC composite material is prepared by dispersing silicon carbide particles in a metal component mainly comprising aluminum. When the section of the interface between the metal component mainly comprising aluminum and the silicon carbide particle is observed, a reaction layer formed from the metal component and silicon carbide is not present at the interface.
