The present invention provides a scroll compressor capable of sufficiently supplying lubricating oil to a compression chamber located between the outermost side surface of the wrap of a fixed scroll and the inner side surface of the wrap of a movable scroll. A fixed-side end plate (24a) of a fixed scroll (24) has a first fixed-side passage (24a5) and a second fixed-side passage (24a6). The first fixed-side passage communicates with the high-pressure space (71). The second fixed-side passage is a passage for supplying lubricating oil from the high-pressure space to the compression chamber (40). A movable-side end plate (26a) of the movable scroll (26) has a movable-side groove (26a2). The movable-side groove intermittently connects the first fixed-side passage and the second fixed-side passage during rotation of the movable scroll. A first fixed-side hole (24c1) of the second fixed-side passage intermittently communicates with the movable-side groove during rotation of the movable scroll. A second fixed-side h
