<P>PROBLEM TO BE SOLVED: To provide a new mixture for powder metallurgy that results in a relatively high density while only requiring a single press and/or single sintering method. Ž<P>SOLUTION: The problem is achieved by a mixture for powder metallurgy having the following componential composition: by mass, 15 to 30% of a valve steel powder, 0 to 10% of Ni powder, 0 to 5% of Cu powder, 5 to 15% of a ferro-alloy powder, 0 to 15% of a tool steel powder, 0.5 to 5% of a solid lubricant, 0.5 to 2.0% of graphite, 0.3 to 1.0% of a temporary lubricant, and the balance being a low alloy steel powder containing 0.6 to 2.0% Mo.
