Abstract
There is provided a sliding member that has sufficient wear resistance and good adhesion to a base formed of a sintered body. The sliding member includes a surface layer formed of a crosslinked fluoropolymer and a base that adheres closely to the surface layer. The base is a sintered body having a full density ratio in the range of 0.75 to 0.96 and is formed of a material having higher thermal conductivity than a fluoropolymer. The surface layer has a thickness in the range of 1 to 300 μm.
