Zusammenfassung:To provide a rolling bearing having excellent rust prevention capability and capable of being used for a long period of time in a highly corrosion environment. A rolling bearing 1 utilized for a power generator which generates power from natural energy or for generator equipment has one or more bearing members which form the bearing having a rust prevention film formed in a predetermined region of a surface of a base material. The rust prevention film is formed by a porous film with a sacrificial anode action against the base material in the whole of the predetermined region. The porous film in a part or the whole of the predetermined region is subjected to sealing treatment which impregnates the porous film with a sealing treatment agent from a surface of the porous film. A surface of a sealing treatment body obtained from the porous film subjected to the sealing treatment is subjected to first coating treatment which coats the surface of the sealing treatment body with epoxy resin coating. A coated surface formed by the first coating treatment is subjected to a second coating treatment which coats the coated surface with urethane resin coating. The sealing treatment agent is formed by diluting the epoxy resin coating at a dilution rate of between 15 and 25%.
