PROBLEM TO BE SOLVED: To provide a film composition for a sliding member capable of forming a film capable of keeping good lubricity even in a state exposed in a severe friction condition for a long time. SOLUTION: The film composition for the sliding member for forming the film on the surface of the sliding member contains a binder resin, an abrasion-inhibiting material and a solid lubricant. The abrasion-inhibiting material is in a form of plate having an aspect ratio expressed with an average particle size/average particle thickness of 5-100, and the average particle size is ≤15.0 μm and Mohs hardness is ≥6. A content of the solid lubricant is 0-15 pts.wt. to the binder resin of 100 pts.wt. A content of the abrasion-inhibiting material is 1-100 pts.wt. to the binder resin of 100 pts.wt. The solid lubricant may be not compounded. The abrasion-inhibiting material is aluminas preferably. COPYRIGHT: (C)2011,JPO&INPIT
