Abstract: Provided is a scroll compressor with enhanced sealing structure of a back pressure chamber. The scroll compressor includes a housing, a fixed scroll fixed to inside of the housing and including a fixed wrap, an orbit scroll including an orbit wrap which forms a compression chamber together with the fixed wrap, a back pressure chamber formed at a frame supporting the orbit scroll, and accommodating refrigerant for pressurizing the orbit scroll to a direction of the fixed scroll, and a sealing ring arranged between the fixed scroll and the orbit scroll to prevent the refrigerant in the back pressure chamber from flowing in or out through a gap between the fixed scroll and the orbit scroll, wherein the sealing ring includes a cut portion cut for the sealing ring to be deformable in a circumferential direction.
