Abstract
A sliding member includes a back-metal layer and a sliding layer on the back-metal layer, and the sliding layer has a sliding surface. The sliding layer includes a synthetic resin and fibrous particles dispersed in the synthetic resin. A volume ratio of the fibrous particles in the sliding layer is 1 to 15%, and the fibrous particles are made of semi-graphite having a nano indenter hardness of 1000 to 5000 MPa. An average aspect ratio of the fibrous particles is not less than 5, where an aspect ratio is defined as a ratio of a major axis to a minor axis of the fibrous particle viewed from the sliding surface. An average grain size of the fibrous particles in cross-sectional view perpendicular to the sliding surface is 5 to 50 μm.
