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.
