Abstract
A sliding member includes a resin overlay layer on a sliding surface side coming into sliding contact with a mating member. The resin overlay layer has a surface roughness parameter Rk satisfying 0.4≤Rk≤1.2, and a surface area ratio S=S2/S1 calculated when an area of an arbitrary measurement field of view is designated by S1 and a surface area of the measurement field of view is designated by S2 satisfies 2.5≤S≤4.5.
