PROBLEM TO BE SOLVED: To provide a solid lubricating film forming method capable of forming an excellent and uniform lubricating film possible to be used for a long time independently of the shape of parts. SOLUTION: This method of forming the solid lubricating film in a surface of the parts comprises a step for preparing the medium having the predetermined dimension and shape, a step for coating the medium with the lubricating agent powder such as molybdenum disulfide, tungsten disulfide, graphite, boron nitride and polytetra fluoroethylene, and a step for coating the surface of the parts with the lubricating agent powder with a physical contact such as rotation, vibration, impact and friction between the medium coated with the lubricating agent powder and the parts.
