A scroll compressor includes fixed and movable scrolls including fixed and movable side end plates and fixed and movable side wraps. The fixed-side end plate includes a first fixed-side passage that communicates with a high-pressure space, and a second fixed-side passage to supply lubricating oil from the high-pressure space to a compression chamber formed between the scrolls. The movable-side end plate includes a movable-side groove that intermittently allows communication between the first fixed-side passage and the second fixed-side passage. The compression chamber includes a first compression chamber, and a second compression chamber located inside the first compression chamber. The second fixed-side passage includes a first fixed-side hole that intermittently communicates with the movable-side groove, and a second fixed-side hole that communicates with the first fixed-side hole and intermittently communicates with the second compression chamber.
