[Problem] To provide a sliding member which has good operatability in a wide temperature range from extremely low to high temperature, and generates less operating sound on a sliding surface, and a grease composition which is used for the sliding member. [Solution] This grease composition contains (A) a straight-chain perfluoropolyether having a kinematic viscosity of 2-110 mm2/s at 40 DEG C, (B)a branched perfluoropolyether having a kinematic viscosity of 2-100 mm2/s at 40 DEG C, and (C) a fluorocarbon resin powder having a primary particle size of 1 microns or less, wherein the contained amount of the fluorocarbon resin powder is 25-40 wt% with respect to the weight of the grease composition, and the weight ratio of the straight-chain perfluoropolyether (A) to the branched perfluoropolyether (B) is 15:85 to 70: 30.
