摘要： A rolling bearing is used for supporting a rocking mechanism or a rotating mechanism, and a film comprising a fluorine-containing polymer having a functional group(s) under a fluidized state or a film comprising a fluorine-containing polyurethane compound under a solid state is formed on at least the track surface of the rolling bearing. Since this film does not contain ions for uniformly dispersing a thickner having non uniform particle sizes such as fluorine based grease of the prior art, breakage of the film between a rolling element and a race is not likely to occur, and wear of a rolling element race resulting from the direct contact between them due to breakage of the film can be reduced. When this film is the same kind of a film as a protective film of the surface of an information recording disk, dust generating components of the film are the same kind of components as those of the protective film, and information recording/reproduction of the information recording disk is not impeded.
