To provide a graphite-added resin-based bearing as a substitution for a sintered copper alloy bearing conventionally used for a fuel injection pump.
In the bearing, on back metal, a sliding layer is baked which comprises 5-60 wt.% of graphite with an average diameter of 5-50 μm, a graphitization degree of 0.6 or more, and an average shape factor (YAVE) of particles excluding fine particles with 0.5 times or less of the average diameter being 1-4, and particles with a shape factor (Y) in the range of 1-1.5 present 70% or more by the number ratio, and the balance polyimide resin and/or polyamideimide resin. YAVE=total [{PMi2/4πAi}]/iY=PM2/4πA, wherein total is the sum of i-pieces of a value in [ ], PM is a peripheral length of one particle, A is a sectional area per one particle, and i is the measured number.
