PROBLEM TO BE SOLVED: To improve the performance of a refrigerant cycling device by securing radiating capability in an intermediate cooling circuit while preventing the occurrence of damage due to liquid compression of a second compressive element. SOLUTION: A compressor 10 includes a motor-driven element 14 and first and second rotary compressive elements 32, 34 driven by the motor-driven element 14 in a closed container 12. The compressor further includes the intermediate cooling circuit 150 for sucking a refrigerant compressed by the first rotary compressive element 32 and discharged in the second rotary compressive element 34 to be compressed and discharged to a gas cooler 153 of a heat exchanger 154, and radiating the refrigerant discharged from the first rotary compressive element 32, and the ratio of radiating capability of refrigerants of the gas cooler 153 to that of an inter cooler 151 of the intermediate cooling circuit 150 is set to 8:2 to 6:4.
