A scroll compressor comprising: a rotating shaft body that is installed in a housing and rotates around an axis of the housing; an eccentric shaft integrated with the rotating shaft so as revolve around the shaft axis at a position eccentric with respect to the shaft axis of the rotating shaft; a movable scroll fixed to the eccentric shaft; a fixed scroll fixed to the housing; a shaft body bearing slidably supporting the rotating shaft body, and an eccentric bearing slidably supporting the eccentric shaft, wherein at least one of the shaft body bearing and the eccentric bearing is a sliding bearing including a back metal, and a sliding layer formed on the back metal by baking, the sliding layer includes 5 to 60 wt% of graphite including particles, with a balance of at least one of polyamide-imide resin and polyimide resin, characterized in that the particles have an average diameter of 5 to 50 μm, a graphitization degree of 0.6 or more, an average shape factor Y AVE of 1 to 4, 70 % or more of the particles in a number ratio have a shape factor Y of 1 to 1.5, and the average shape factor Y AVE is defined by Y AVE = SUM PMi 2 / 4 π Ai / i fine particles with less than or equal to 0.5 times of the average diameter are not considered in calculating Y AVE, where the shape factor Y is defined by Y = PM 2 / 4 πA PM denotes a periphery length of a single particle, A denotes a cross-sectional area of a single particle, i denotes number of measured particles, and SUM denotes a summation of formulas in [] for i particles. a rotating shaft body that is installed in a housing and rotates around an axis of the housing; an eccentric shaft integrated with the rotating shaft so as revolve around the shaft axis at a position eccentric with respect to the shaft axis of the rotating shaft; a movable scroll fixed to the eccentric shaft; a fixed scroll fixed to the housing; a shaft body bearing slidably supporting the rotating shaft body, and an eccentric bearing slidably supporting the eccentric shaft, wherein at least one of the shaft body bearing and the eccentric bearing is a sliding bearing including a back metal, and a sliding layer formed on the back metal by baking, a back metal, and a sliding layer formed on the back metal by baking, the sliding layer includes 5 to 60 wt% of graphite including particles, with a balance of at least one of polyamide-imide resin and polyimide resin, characterized in that the particles have an average diameter of 5 to 50 μm, a graphitization degree of 0.6 or more, an average shape factor Y AVE of 1 to 4, 5 to 60 wt% of graphite including particles, with a balance of at least one of polyamide-imide resin and polyimide resin, characterized in that the particles have an average diameter of 5 to 50 μm, a graphitization degree of 0.6 or more, an average shape factor Y AVE of 1 to 4, 70 % or more of the particles in a number ratio have a shape factor Y of 1 to 1.5, and the average shape factor Y AVE is defined by Y AVE = SUM PMi 2 / 4 π Ai / i fine particles with less than or equal to 0.5 times of the average diameter are not considered in calculating Y AVE, where the shape factor Y is defined by Y = PM 2 / 4 πA PM denotes a periphery length of a single particle, A denotes a cross-sectional area of a single particle, i denotes number of measured particles, and SUM denotes a summation of formulas in [] for i particles.
