PROBLEM TO BE SOLVED: To provide a gas compressor having an oil separator which can provide a sufficient oil separation performance. SOLUTION: Discharge passages 103A and 103B are united into one by an introduction pipe line 201, and refrigerant gases respectively flowing in from the discharge passage 103A and the discharge passage 103B collide with each other. Then, the refrigerant gas is swirled in a primary separation chamber 214. Oil mist of high specific gravity is urged in the centrifugal direction by the centrifugal separation effect by the swirl, and deposited on an inner wall of an outer cylinder 211. Next, the refrigerant gas with remaining oil therein is further led to a secondary separation chamber 219. In the secondary separation chamber 219, the refrigerant gases from both sides collide with each other.
