Abstract: A sliding member includes a bearing alloy layer, a solid lubricant layer, particles and a covering portion. The solid lubricant layer is provided on a sliding surface side of the bearing alloy layer and is deposited on the bearing alloy layer. The particles form the solid lubricant layer and are made of metal sulfide. The covering portion is provided over outermost surfaces of the particles on the sliding surface side and are made of metal oxide including the same metal element as a metal element constituting the particles.

Abstract: A bearing member according to an embodiment of the present invention is formed into a single cylindrical shape or a cylindrical shape divided into arcs along a circumferential direction, and is assembled to a housing on an outer peripheral side of the bearing member. The bearing member includes an outer peripheral surface provided on a side opposed to an inner peripheral surface of the housing. A maximum height Rz (μm) of a surface roughness of the outer peripheral surface is set as 2.00 μm≤Rz≤4.00 μm, and a value of ratio between an average protruding-peak height Rpk (μm) and a load length rate Mr1 (%), that is a load curve parameter for the surface roughness is set as 0.010≤Rpk/Mr1≤0.100.
