PROBLEM TO BE SOLVED: To improve the wear resistance of an injection molding and sintering material of ferrous metal powder. SOLUTION: Hard grains 5 in the amount of 3.0-6.0wt.% are dispersed in a ferrous base metal powder for injection molding and sintering material of metal powder. The ferrous base metal powder 6 is composed of one or∞2 kinds selected from stainless steel, pure iron, nickel-containing iron, cobalt- containing iron, and chromium-molybdenum steel. Further, the hard grains 5 are selected from ceramic materials, such as titanium nitride(TiN) and chromium nitride(CrN), or from intermetallic compounds.
