PROBLEM TO BE SOLVED: To provide a compressor for properly cooling depending on calorie (a temperature, a gas amount) of a gas discharged from a compressor main body to reduce required motive power used for the cooling. SOLUTION: The compressor includes the compressor main body 1 compressing suction gas sucked from a suction flow passage 3, and a discharge flow passage 5 supplying the gas discharged from a discharge port 1b of the compressor main body 1 to a gas supply destination side. The discharge flow passage 5 has a temperature detector 7 detecting a discharged gas temperature, a heat exchanger 6 cooling the discharged gas, and a cooling fan 9 flowing the cooling air against the heat exchanger 6. A computing unit 8 is provided to control the revolution number of the cooling fan 9 so that the discharged gas becomes a predetermined temperature defined in advance. By the constitution, cooling is properly performed depending on the calorie of the gas discharged from the compressor main body 1, so as to reduce the required motive power used for the cooling.
