Provided is a solid lubricant having high durability. The solid lubricant comprises a material having a hexagonal crystal structure. A ratio of a plane other than (002) plane to (002) plane of the solid lubricant at an interface with a base material to be coated is higher than a ratio of a plane other than (002) plane to (002) plane on a surface of the solid lubricant. Alternatively, a ratio of a peak intensity of X-ray diffraction for the plane other than (002) plane to a peak intensity of X-ray diffraction for (002) plane of the solid lubricant at the interface with the base material is higher than a ratio of a peak intensity of X-ray diffraction for the plane other than (002) plane to a peak intensity of X-ray diffraction for (002) plane on the surface of the solid lubricant.

A rolling bearing includes an outer ring having an outer surface configured to be fitted into a first component, an inner ring having an inner surface configured to be fitted onto a second component, at least one rolling element arranged between the outer ring and the inner ring, and an antimony-free composite coating on the outer surface of the outer ring and/or the inner surface of the inner ring. The antimony-free composite comprises a binder and polytetrafluorethylene as a solid lubricant.
