A scroll compressor includes a compression mechanism including fixed and movable scrolls. The fixed and movable scrolls have end plates and spiral laps. The laps are engaged to form a compression chamber. The end plates are in pressure contact around the compression chamber to form a thrust sliding surface. The thrust sliding surface has an oil groove extending around the compression chamber. High-pressure refrigerating machine oil is supplied to the oil groove. During orbiting of the orbiting scroll, at least in a region serving as a suction space of fluid in an outer peripheral portion of the compression chamber, an outer seal length from an outer peripheral edge of the oil groove in the thrust sliding surface to an outer edge of the movable end plate is smaller than an inner seal length from an inner peripheral edge of the oil groove to a peripheral edge of the compression chamber. |
