A compressor includes a discharge housing member, which includes a discharge chamber and an oil separation chamber. The discharge housing member includes a cylindrical wall defining the discharge chamber and the oil separation chamber. The discharge chamber includes a partition that is continuous with and protrudes from the cylindrical wall. The cylindrical wall extends from an upper section of the discharge chamber toward a lower section of the discharge chamber. The cylindrical wall includes a communication hole connecting the discharge chamber to the oil separation chamber. The partition extends from the upper section of the discharge chamber toward the lower section of the discharge chamber and defines a first space and a second space in the discharge chamber. The first space and the second space are connected to each other at least at the lower section of the discharge chamber through a clearance between the partition and the circumferential wall.
