Zusammenfassung:	To provide a rolling bearing excellent in peeling resistance even under severe sliding circumstances.SOLUTION: A rolling bearing includes an inner ring 11, an outer ring 12, and a plurality of rolling elements 13a, 13b for rolling between the inner ring 11 and the outer ring 12. The bearing has a hard film on the surface of at least one bearing member selected from the inner ring 11, the outer ring 12, and the rolling elements 13a, 13b, and is used under the boundary lubrication condition that the hard film has rolling slide contact with the other bearing member. The hard film has a surface layer formed of diamond-like carbon, and the hydrogen content of the surface layer is over 5 atom% and 30 atom% or lower.SELECTED DRAWING: Figure 3 【課題】過酷な摺動環境下でも耐剥離性に優れる転がり軸受を提供する。【解決手段】転がり軸受は、内輪１１と、外輪１２と、内輪１１と外輪１２との間を転動する複数の転動体１３ａ、１３ｂとを備えてなる転がり軸受であって、内輪１１、外輪１２、および転動体１３ａ、１３ｂから選ばれる少なくとも一つの軸受部材の表面に硬質膜を有し、該硬質膜が他の軸受部材と境界潤滑で転がり滑り接触する条件で使用される軸受であり、硬質膜は、ダイヤモンドライクカーボンからなる表面層を有し、表面層の水素含有量が、５原子％をこえて３０原子％以下である。【選択図】図３
