Abstract: Provided is a sliding member having: a back metal layer; and a sliding layer on the back metal layer. The sliding layer includes a porous sintered layer and a resin composition. The sintered layer includes Ni—P alloy phase and granular steel phase made of a carbon steel including 0.3-1.3 mass % of carbon and having a structure of: ferrite phase; and perlite phase, or perlite phase and cementite phase. The Ni—P alloy phase binds the steel phases with one another and/or binds the steel phases with the back metal layer. The steel phase includes a low perlite phase part in a surface. The low perlite phase part has an area ratio of the perlite phase lowered by 50% or more compared with a total area ratio of the perlite phase and the cementite phase at a central part of the steel phase when observed in a cross-section.

Abstract: Provided is a sliding member including a steel back metal layer and a sliding layer with a porous sintered layer and a resin composition. The porous sintered layer includes granular Fe or Fe alloy phase and Ni—P alloy phase for binding the Fe or Fe alloy phase grains with one another. The steel back metal layer is made of a carbon steel including 0.05-0.3 mass % of carbon and having a structure composed of ferrite phase and pearlite phase, and includes a low pearlite phase part in a surface thereof on a side of the sliding layer. The low pearlite phase part has a ratio of the pearlite phase is lowered by 50% or more compared with the pearlite phase at a central part in a thickness direction of the steel back metal layer. The Ni—P alloy phase may cover the entire surface of the steel back metal layer.
