Zusammenfassung:PROBLEM TO BE SOLVED: To form a lubrication film coating the surface of a base powder with high accuracy at low costs.SOLUTION: In a method of producing a powder 10 for manufacture of a sintered body consisting of a metal powder 11, as a base powder B, surface-coated with a lubrication film 12, a solid lubricant 13 is molten with frictional heat generated in mixing the metal powder 11 with the solid lubricant 13, and a solution 14 produced in the melting is coated to the surface of the metal powder 11. The mixing of the metal powder 11 and the solid lubricant 13 is carried out in a medialess condition.
