Zusammenfassung:	PROBLEM TO BE SOLVED: To correspond to the request that, in JR conventional lines and each nongovernmental railroad line, the speed of electric rolling stocks is diversified from low speed to high speed, and a slider capable of corresponding to a high speed region close to 160 km/H is desired. SOLUTION: A powder raw material composed of, as wear resistant and arc resistant components, simple substance Cr of 3 to 20 wt.%, as lubricating components, graphite or one or plural kinds of metallic sulfides (MoS2 and WS2) of 2 to 8 wt.%, as lubrication strengthening components, Bi of 2 to 6 wt.%, as sintering base components, P of
