Abstract: To provide a rolling bearing having superior handling property and creep resistance. A rolling bearing 1 includes an inner ring 2 and an outer ring 3 that are raceway rings, and a plurality of balls 4 interposed between the inner ring and the outer ring. The outer ring 3 is fitted to a housing 10. The rolling bearing 1 includes a surface coating film 8 on an outer ring outer diametrical surface 3a that is a fitting surface with the housing 10. The surface coating film 8 contains: a binder containing two or more kinds of thermosetting resins having different average molecular weights; and a solid lubricant. The solid lubricant contains molybdenum disulfide, polytetrafluoroethylene resin, and graphite.
