PROBLEM TO BE SOLVED: To provide a scroll compressor with high reliability in which a key groove for sliding an Oldham key is formed in a stationary scroll and lubrication is reliably performed on a sliding face of the key and the key groove.SOLUTION: A scroll compressor 10 comprises: a stationary scroll 31 having a stationary side mirror plate 311, a stationary side lap 312 and a peripheral edge 313; a movable scroll having a movable side mirror plate and a movable side lap; and an Oldham joint having a ring part and a second key part. A compression chamber is formed between the stationary lap and the movable lap. A first oil groove 313d supplied and held with oil from an oil storage space communicated with a high-pressure compression chamber on an always sliding face R1 always contacting a front face of the movable side mirror plate is formed at the peripheral edge opposed to the front face of the movable side mirror plate. A second key part sliding space S2 in which the second key part slides is formed on an outer periphery side than the first oil groove. A second oil groove 313e communicated with the second key part sliding space is formed on the outer peripheral side than the first oil groove and on an inner peripheral side than the second key part sliding space.
