PROBLEM TO BE SOLVED: To provide an amorphous composite material which is manufactured at a low cost, can be made into a large size and various forms, and has ductility and high fracture toughness. SOLUTION: This amorphous matrix composite material includes ductile metal powders dispersed and unified in and with amorphous alloy powders, wherein the amorphous alloy powder includes all alloys which can be produced into an amorphous alloy structure, and the ductile metal powder includes all sorts of materials which have lower deformation stress than that occurring when the amorphous alloy powders are molded in a supercooled period, and is contained in the composite material in amount of 0.1 vol.% to 40 vol.%. The amorphous alloy includes Ni, Ti, Zr, Fe, and the like, and the ductile metal powder includes a copper powder or the like. COPYRIGHT: (C)2003,JPO
