(57) [Summary] [PROBLEMS] To extend the life of a DLC layer by increasing the adhesion of the DLC layer on the premise of a rolling sliding component covering the DLC layer. A diamond-like carbon (W-DLC) layer containing tungsten (W) is provided on a surface of metal base materials (2, 3) via a chromium (Cr) layer (7). 8 are stacked. In this case, since the Cr layer 7 is interposed between the metal base materials 2 and 3 and the W-DLC layer 8, the W-D As a result, the adhesion of the LC layer 8 is improved, and the operation can be stabilized for a long time. |
