PROBLEM TO BE SOLVED: To provide a bearing ring for a rolling bearing capable of sufficiently coping with a corrosion environment. SOLUTION: In a bearing ring for a rolling bearing, a tetra-fluoroethylene resin film 4 is formed in the total peripheral surface of the bearing ring 1 formed by an anti-corrosive material, an electroless nickel plating film 3 is interposed between the total peripheral surface of the bearing ring 1 except a raceway 2 and the tetra-fluoroethylene resin film 4, also grease 5 is applied onto the tetra-fluoroethylene resin film 4 on the raceway 2.
