PROBLEM TO BE SOLVED: To improve heat dissipation, by fusing specified quantity respectively of metallic particles and resin particles using heat source, in a frictional material used for a clutch and others of an automobile or others, and by inter-combining metallic particles, resin particles, or a metallic particle and a resin particle to form a pore with specified volume. SOLUTION: This frictional material is composed of 30-80 vol.% of metallic particle M, such as high strength brass, alloy steel, tin bronze, aluminum alloy, or titanium, and 10-60 vol.% of resin particle P, such as polybutyleneterephthalate, nylon, polyketone, or polyacetal. Furthermore, both particles are fused or semi-fused by a heat source, metallic particles M, resin particles P, or metallic particle M and resin particle P, respectively, are chemically and mechanically inter-combined, and a frictional material with a pore H of 10-40 vol.% is provided. In this case, the grain diameter of used metallic particle M is 2-200μm, and the grain diameter of resin particle P is 30-300μm. Therefore, each particle can be evenly dispersed, and characteristic as frictional material is stabilized.
