Abstract
An object of the present invention is to provide a sliding member coated with a DLC coating in which microfractures on the sliding surface thereof due to the progression of cracks are less likely to occur, and in which an increase in abrasive wear can be reduced. The present invention achieves the above-mentioned object by a sliding member having a DLC coating on the outer peripheral surface thereof, wherein an S band derived from spbonding is observed in the DLC coating in addition to a G band derived from the graphite structure and a D band derived from the defects of the graphite structure, and these bands satisfy specific relationships.
