Provided is a starting material powder that is for powder metallurgy and that is capable of improving strength and density, and preventing sintered-body contamination, surface defects, and decarburization. The starting material powder for powder metallurgy is for use in the production of a sintered body obtained by sintering at 500°C or higher, wherein a metal powder and a lubricant are mixed with one another, and the lubricant is melamine cyanurate or terephthalic acid. Or, the starting material powder for powder metallurgy is for use in the production of a sintered body obtained by sintering at 500°C or higher, wherein a metal powder, a first lubricant and a second lubricant are mixed with one another, the first lubricant is melamine cyanurate or terephthalic acid, and it is preferable for the second lubricant to be erucic acid amide or stearic acid amide. |
