Abstract

A sliding member includes a metallic substrate, a porous layer formed on a surface of the metallic substrate, and a sliding layer that covers the porous layer. The porous layer is made of a metal itself or an alloy composition. The sliding layer is made of a lead-free resin composition. The resin composition contains an essential additive, optionally an optional additive, and a fluororesin. The essential additive is any one of a combination of a zinc compound and a carbon fiber, a combination of a zinc compound and an iron oxide, and a combination of a zinc compound, a carbon fiber and an iron oxide. A total content of the essential additive and the optional additive is 10 vol % or more and 35 vol % or less in the resin composition.
