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.
