Abstract

Provided is a sliding member having a steel back metal layer and a sliding layer. The sliding layer includes a resin composition and a porous sintered layer including Fe or Fe alloy phase particles and a Ni—P alloy phase functioning as a binder. The steel back metal layer is made of a carbon steel including 0.05 to 0.3 mass % carbon and includes a ferrite phase and a pearlite phase. A central portion in a thickness direction of the steel back metal layer includes not greater than 30 volume % of the pearlite phase. The steel back metal layer includes a high pearlite phase portion in its surface facing the sliding layer. The high pearlite phase portion includes not less than 50 volume % of the pearlite phase.
