PROBLEM TO BE SOLVED: To provide a high nitrogen stainless steel powder for solidification molding which is free of Ni or reduced in Ni, and is excellent in corrosion resistance, and to provide a method for producing the high nitrogen stainless steel powder. SOLUTION: The high nitrogen stainless steel powder for solidification molding excellent in corrosion resistance is obtained by absorbing nitrogen into alloy powder comprising, by mass, 0 to 5.0% Ni and 10.0 to 40.0% Cr and incorporating≥0.5% N therein, and in which the maximum size of CrN at the inside of the powder is 3μm. Also, the high nitrogen stainless steel powder for solidification molding excellent in corrosion resistance is obtained by absorbing nitrogen into alloy powder comprising 0.1 to 15.0% Mn and 0.1 to 20.0% Mo, and further comprising 0.1 to 10.0% Cu, 0.3 to 2.0% Si and≤0.2% C in addition to the above componential composition and incorporating≥0.5% N therein, and in which the maximum size of CrN at the inside of the powder is 3μm.
