The object of the present invention resides in providing a sliding member having a sliding layer on the sliding surface which is further improved in sliding characteristics, particularly, wear resistance and, besides, improved in bonding force of the sliding layer. In the present invention, a plating layer 1a is provided on the surface of a substrate 1 comprising stainless steel or carbon steel, and a porous layer 2 is provided by spreading metal powders of a copper alloy or the like on the surface of the plating layer 1a and sintering the metal powders. Then, the porous layer 2 is impregnated and coated with a sliding layer 3 containing PBI and 1-70 vol % of a solid lubricant.
