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 consists of a pitch-based carbon fiber and a fluororesin, and assuming weight of the resin composition as 100, more than 10 weight % and 35 weight % or less of the pitch-based carbon fiber is contained.

Disclosed herein is a sliding member that has a coating layer serving as a sliding surface thereof so that even when foreign matter enters between the coating layer and a partner member, smoothness between them is maintained to prevent the occurrence of seizing. When the coating layer has an elastic recovery ratio of less than 60%, foreign matter that has entered between the coating layer and the sliding surface of a partner member is efficiently embedded in the coating layer. When the coating layer is formed of a resin composition, the resin composition contains a binder resin, a solid lubricant, and metal particles having a Young's modulus of 10 GPa or more but 100 GPa or less.

Slide bearings and methods of producing slide bearings are disclosed. The slide bearing has a metal support and a sliding layer. No other layer is in contact with the sliding layer. The sliding layer is applied directly to the metal support. The sliding layer comprises a mixture of at least two polymers P1 and P2, wherein P1 is a fluoropolymer. P2 is a non-fluorinated thermoplastic polymer.

A thrust washer is provided with a ring-shaped portion that surrounds an insertion hole, the thrust washer is provided with a sliding surface and an oil groove configured to allow lubricating oil to flow in, the oil groove is provided with an opening portion configured to allow the lubricating oil to flow in from the insertion hole side in an inner peripheral end side, an outer periphery end side of the ring-shaped portion of at least one of the oil groove is provided with an oil stop wall which is configured to suppress flow of the lubricating oil toward an outer periphery side of the ring-shaped portion, and a sliding area ratio of each of the sliding surfaces to a projection plane in plan view of the ring-shaped portion is provided within a range of from 60% to 85%
