Provided is a sliding member comprising: a steel back metal layer; and a sliding layer including a porous sintered layer and a resin composition. The porous sintered layer includes Fe or Fe alloy granules and a Ni—P alloy part functioning as a binder for binding the Fe or Fe alloy granules with one another and/or for binding the Fe or Fe alloy granules with the steel back metal layer. The steel back metal layer is made of a carbon steel including 0.05 to 0.3 mass % of carbon, and includes: a non-austenite-containing portion having a structure of a ferrite phase and perlite formed in a central portion in a thickness direction of the steel back metal layer; and an austenite-containing portion having a structure of a ferrite phase, perlite and an austenite phase formed in a surface portion of the steel back metal layer facing the sliding layer.
