Abstract
A polytetrafluoroethylene is added to a base resin consisting essentially of polyether ether ketone so that the proportion of polytetrafluoroethylene becomes 0.1 to 50% by weight based on the resin layer and dispersed in the form of particles in the base resin, whereby when the resulting resin layer is bonded to a backing metal to form a composite bearing, the peel strength of the resin layer per se and mechanical strength such as bonding force or the like between the backing metal and the resin layer can be inhibited from being deteriorated. When polytetrafluoroethylene having a molecular weight of 300,000 to 500,000 is used, it can be more easily dispersed in the form of particles in the base resin.
