Abstract

A sliding member for a journal bearing is provided. A sliding layer includes fibrous particles dispersed in a synthetic resin, and has a sliding surface side region and an interface side region. The particles have an average particle size Dand Drespectively in an axial and circumferential cross-section in the sliding surface side region, and Dand Drespectively in axial and circumferential cross-sections in the interface side region. Dand Dare 5-30 μm, and Dand Dare 5 to 20% of respectively Dand D. A dispersion index of the particles having the major axis length of 20 μm or longer is 5 or more, both in the sliding surface side region in view of the axial cross-section and in the interface side region in view of the circumferential cross-section.
