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, on the outer peripheral sliding surface thereof, a DLC coating in which the amount of plastic deformation work as measured by a nanoindentation test is within a specific range.
