PROBLEM TO BE SOLVED: To provide a compressor which can separate oil, while the number of parts is reduced and the size of the device is reduced. SOLUTION: A rotor 31 has: a first passage 51 and a second passage 52 which are extended in an axial direction, and are not overlapped with each other when seen from an axial direction; and an oil separating mechanism G1 constituted of a third passage 53 extended in a direction orthogonal to the first and second passages to connect the first passage with the second passage. Therefore, mixture of oil and refrigerant gas passes through the first passage 51 and then is collided with an inner face of the third passage 53. At this time, the oil is liquified and returned to the first passage 51, and on the other hand, the refrigerant gas passes through the third passage 53 and then passes through the second passage 52.
