Abstract

A sliding member includes a carbon transfer layer and can superiorly effectively decrease friction and reduce wear. A method produces the sliding member. The sliding member includes a substrate and a carbon transfer layer. The carbon transfer layer is disposed on the surface of the substrate and includes both spbonded carbon and spbonded carbon. The carbon transfer layer preferably has a ratio sp/(sp+sp) of the spbonded carbon to the totality of the spbonded carbon and the spbonded carbon of 0.1 or more.
