Abstract

See full text

A sliding member (10) includes a base material (12), a porous sintered layer (14) provided on the base material (12), and a resin layer (16) impregnated into the porous sintered layer (14) and provided on the porous sintered layer (14). In the porous sintered layer (14), a porosity decreases from a second surface (S2) opposite to a first surface (S1) closer to the base material, toward the first surface (S1), the first surface and the second surface each being one of end surfaces in the thickness direction, and a decrease rate of the porosity in the thickness direction (Z) in a first region (E1) occupying 50% or more of the thickness of the porous sintered layer (14) from the second surface (S2) toward the first surface (S1) is larger than a decrease rate of the porosity in the thickness direction (Z) in a second region (E2) other than the first region (E1) in the porous sintered layer (14).
