PROBLEM TO BE SOLVED: To provide an accurate slide bearing improved in productivity without processing gate scars. SOLUTION: In this bearing, a sintered metal 2 is used for a peripheral part of the bearing, and a resin layer 3 is formed by insert-molding of a resin material in a sliding part of the peripheral part of the bearing. In this resin layer, (linear expansion coefficient of the resin material) x (thickness of the resin layer) is set at 0.15 or less. The resin layer is a resin layer formed by insert-molding through a tunnel gate, and has a plurality of axial grooves 4A and 4B in the bearing sliding surface thereof, and tunnel gate scars 5 are formed each other in a bottom part position of these grooves.
