An object is to obtain a scroll compressor that prevents wear and seizure between an orbiting scroll and a thrust plate in a thrust structure in which cast iron is used for the orbiting scroll and the thrust plate formed from a steel plate is disposed at a back side of the orbiting scroll, and that is highly reliable. A scroll compressor includes a body container that is a hermetically sealed container; a fixed scroll that is fixed to an upper portion of an inside of the body container; an orbiting scroll 102 that is disposed below the fixed scroll and that is made of a cast-iron-based material; a rotary drive shaft including an oil passing hole that connects an upper side and a lower side in the shaft; a frame that is fixed to an inner peripheral surface of the body container to slidably support the orbiting scroll 102; a thrust plate that is disposed between a lower surface of the orbiting scroll 102 and a thrust support surface of the frame and that is made of a steel-plate-based material; an Oldham ring that is accommodated in the frame; and an orbiting-side Oldham groove 102d that guides the Oldham ring, wherein a circumferential groove 102f that communicates with the orbiting-side Oldham groove 102d is formed in the lower surface of the orbiting scroll 102. |
