PROBLEM TO BE SOLVED: To provide an oil injection type compressor which can intend to make cooling efficient without requiring local cooling defect of a driving motor by disappearing air cavity in a cooling jacket of the driving motor. SOLUTION: In the oil injection type compressor provided with an oil circulating flow passage 12 which comes into fluid communication with the compressor itself 20 from an oil separation collector 10 and in which an oil cooler 13 which cools oil separated with the oil separation collector 10 is intervened, it is configured so as to intervene the cooling jacket 2b of the driving motor intermediate on downstream side of the oil circulating flow passage 12 in fluid communication with the compressor itself 20 from the oil cooler 13 and at the same time to bring a gas venting hole 4 provided on an upper portion of the cooling jacket 2b into fluid communication with a gas suction port 30a provided on downstream side from a suction regulator 7 of a suction flow passage 8 by the gas venting flow passage 3.
