Abstract: A multi-layer sliding member (1) includes a backing plate (2) formed from a steel plate, a copper-plated or nickel-plated layer (4) formed on one surface (3) of the backing plate (2), a porous sintered metal layer (5) integrally bonded to the surface (3) of the backing plate (2) through the layer (4), and a coating layer (8) filling pores (6) and coating on the surface (7) of the porous sintered metal layer (5) and formed from a synthetic resin composition. The synthetic resin composition contains a PTFE as a main component and further contains, as additives, 5 to 30% by mass of a thermotropic liquid crystal polymer, 5 to 12% by mass of a polyarylketone resin, 5 to 12% by mass of a melt moldable fluororesin, and 1 to 5% by mass of a polyimide resin.
