PROBLEM TO BE SOLVED: To industrially manufacture nano particle powder of a ferromagnetic material suitable for high-density magnetic recording with good productivity. SOLUTION: The method of manufacturing the alloy particulates for magnetic recording medium comprises preparing an F.M-containing solution dissolved with at least one metal salt among the chloride, sulfate, nitrate or carbonate of transition metals F (F denotes one or two kinds of Fe or Co) and the chloride of platinum group metals M (M denotes one or two kinds of Pt or Pd) in a phase solution of a hydrophilic organic solvent and water and regulated to a pH≥7 and adding a reducing agent to this F.M-containing solution to reduce the F and M in the solution to the F<SB>x</SB>M<SB>100-x</SB>alloy particulates (where 30≤x≤70).
