PROBLEM TO BE SOLVED: To provide an inexpensive W-based high specific gravity composite material solved in the defects of the conventional integrated type material as the use for damping, having a high damping capacity which has not been exhibited heretofore, high in workability, easy to be formed into various shapes and having a high radiation shielding capacity which has not been exhibited heretofore as the use for radiation shielding. SOLUTION: By obtaining a sintered body containing one or more kinds selected from In, Sn, Sb, Tl and Bi of 15 to 90 wt.%, and the balance W or a material in which one or more kinds selected from In, Sn, Sb, Tl and Bi of 15 to 90 wt.% are infiltrated into a W skeleton containing one or more kinds selected from Ni, Cu and Co of 0.3 to 3 wt.% on the surface, the inexpensive high specific gravity composite material provided with good damping and radiation shielding properties can be obtained.
