Disclosed is a compressor which is provided with a centrifugal separation-type oil separator, and which makes it possible to avoid an increase in the number of components that accompanies the inclusion of the oil separator. The compressor is provided with a movable member (2) which moves in accordance with the rotation of a shaft (1), and a fixed member (4) which forms a compression chamber (3) together with the movable member, and the compressor compresses a working fluid in the compression chamber (3) in accordance with the movement of the movable member (2). In the compressor, an oil separator (14) which introduces the working fluid compressed in the compression chamber and separates oil from the working fluid is integrally formed with the fixed member (4). In a vane compressor, the fixed member (4) is formed by a cylinder part (4a) which accommodates the movable member (2) and by a rear-side block (4b) which is integrally formed with this cylinder part (4a), and the oil separator (14) is integrally provided with the rear-side block (4b). An oil separation chamber (22) of the oil separator (14) is covered with a tube part (5b) of a shell member (5) which forms a housing.
