Zusammenfassung:	To provide a roller bearing that can be improved in wear resistance and in lubrication performance.SOLUTION: The roller bearing comprises an inward member, an outward member, rollers 4, 5 intermediated between raceway surfaces of the inward member and the outward member, and a cage holding the rollers 4, 5. The roller bearing further comprises a DLC film 9 on the outer periphery of each of the rollers 4, 5. The DLC film 9 has three-layer structure of a metal layer 9a, an intermediate layer 9b as a metal and DLC mixed layer, and a surface layer 9c sequentially from the base material side of each of the rollers 4, 5. A recessed portion 16 in which lubricant is held is provided in the surface layer 9c of the DLC film 9, and the recessed portion 16 includes a polymer-like carbon. The nanoindentation hardness of the recessed portion 16 is 13 GPa-16 GPa.SELECTED DRAWING: Figure 3B 【課題】潤滑性能の向上を図り耐摩耗性を向上することができるころ軸受を提供する。【解決手段】ころ軸受は、内方部材と、外方部材と、これら内方部材、外方部材の軌道面間に介在するころ４，５と、ころ４，５を保持する保持器とを備える。ころ４，５の外周面にＤＬＣ膜９を有する。ＤＬＣ膜９は、ころ４，５の基材側から順に、金属層９ａ、金属とＤＬＣの混合層である中間層９ｂ、および表面層９ｃの３層構造である。ＤＬＣ膜９の表面層９ｃに潤滑剤が保持される凹み部１６が設けられ、この凹み部１６はポリマーライクカーボンを含む。凹み部１６のナノインデンテーション硬さは１３ＧＰａ～１６ＧＰａである。【選択図】図３Ｂ
