PROBLEM TO BE SOLVED: To provide a multilayer bearing using a resin composition which does not include lead or the like, achieving an excellent dynamic friction coefficient and wear resistance and having stable sliding characteristics in high contact pressure conditions. SOLUTION: The multilayer bearing 1 includes a metal substrate 2, a porous layer formed on one surface of the metal substrate 2, and the resin composition 4 impregnated into and covered with the porous layer. The porous layer is a sintered layer of polygonal soft metal powder 3 (copper-tin alloy powder). The resin composition 4 includes PTFE resin, carbon fiber 4a and a calcium compound.
