This invention provides a sliding part includes a resin layer (12) on the base material. Said resin layer (12) includes resin bonding agent (21) and solid lubricant (22, 23) in 40-60 % (percent by volume ). The solid lubricant (22, 23) includes graphite and molybdenum dioxide and meets the following formula: (a)-(c). (a) the ratio of Xg (average particle size of graphite) with the Xm (average particle size of molybdenum dioxide ) meets the following formula:2<=Xg/Xm<=10. (b) the ration of Vg(percent by volume) with the Vm(percent by volume)meets the following formula:0.2<=Vg/Vm<=2.0 (c) the total area valve of the solid lubricant meets the following formula:Vg/Xg+Vm/Xm<=0.55. |
