Abstract:
Disclosed herein is a sliding member for an internal-combustion engine of an automobile or the like. The sliding member has excellent sliding properties due to high oleophilicity of its sliding surface achieved by adjusting the surface texture of a resin layer forming the sliding surface, which makes it possible to effectively prevent wear or seizure of the sliding member and a counterpart sliding member thereof. The sliding member includes a resin layer provided on a surface of a base material, in which the resin layer has a surface roughness of 1.05 or more, preferably 1.07 or more. The mean spacing (s) between local peaks of the resin layer may be in the range of 2 μm or more but 12 μm or less, but may be preferably in the range of 2 μm or more but 10 μm or less. Further, the mean height (Rc) of the resin layer may be in the range of 0.5 μm or more but 5.0 μm or less, but may be preferably in the range of 0.5 μm or more but 3.0 μm or less.
