PROBLEM TO BE SOLVED: To provide a double-layer bearing capable of suppressing the deterioration of mechanical strengths such as peel strength of a resin layer itself or bonding power of a back plate to the resin layer of the wet type double layer bearing prepared by joining the resin layer containing polytetrafluoroethylene added to a base resin of polyetheretherketone to the back plate. SOLUTION: This double-layer bearing is obtained by adding 0.1-50 wt.% of polytetrafluoroethylene to polyetheretherketone which is a base resin and dispersing the polytetrafluoroethylene in the form of a granular shape. The dispersion into the form of the granular shape can preferably be readily carried out by using the polytetrafluoroethylene having 300,000-500,000 molecular weight. |
