摘要	A scroll compressor includes a fixed scroll, an orbiting scroll, a suction section, a discharge section, and an electric motor. A sliding surface of a scroll is formed outside a wrap with a depression section depressed with respect to a sliding surface and a flange section elevated with respect to the depression section. The flange section is a remaining region in a protruding region disposed outside a referential perfect circle, the remaining region being other than a region continuing to an end of an involute curve of a scroll formed with the flange section, the referential perfect circle having a radius set to a distance between the center of the scroll formed with the flange section and the end of the involute curve. The scroll compressor enhances reduction of the sliding loss with a simple structure and reduction of the refrigerant leakage loss in the entire compression chambers.
