摘要： The present invention provides a rolling bearing in which the peeling resistances of a DLC film formed on raceway of inner and outer rings and a sliding surface of a cage are improved to allow the intrinsic properties of the DLC film to be displayed so that the rolling bearing is excellent in its resistance to seizing, wear, and corrosion. A rolling bearing (1) has an inner ring (2), an outer ring (3), a plurality of rolling elements (4), and a cage (5). A hard film (8) is formed on a curved surface such as a raceway (2a) of the inner ring (2), a raceway (3a) of the outer ring (3), and the like. The hard film (8) is composed of a foundation layer, composed mainly of Cr, which is formed directly on the curved surface, a mixed layer, composed mainly of WC and DLC, which is formed on the foundation layer, and a surface layer, composed mainly of the DLC, which is formed on the mixed layer. In the mixed layer, the content rate of the WC becomes lower continuously or stepwise in a direction from the side of the foundation layer toward the side of the surface layer, and the content rate of the DLC becomes higher in the above-described direction.
