An overlay layer 3 comprising MoS<SUB>2 </SUB>as a solid lubricant and PAI resin as a binder resin is formed on a flattened surface of a bearing alloy layer 2, and a helical groove 4 and annular projections 5 are formed as an uneven configuration in and on the surface of the overlay layer. In accordance with the invention, a regular uneven configuration is formed on the surface of the overlay layer to allow a lubricant oil to be secured in recesses of the uneven configuration, allowing a seizure resistance to be improved. The bearing alloy layer is machined to have a flat surface having a fine roughness on its surface which represents a boundary with an overlay layer, whereby individual convex areas of the overlay layer are evenly subject to a plastic deformation, allowing the fitting property response of the sliding bearing to be improved.
