A problem to be solved by the present invention is that the temperature of a refrigerant discharged from a compression section can be detected more exactly without being influenced by variable factors existing around the compression section. In a rotary compressor 1 having a motor 6 and a compression section 3 provided in a closed container 2, and also having a discharge pipe 26 provided in an upper part of the closed container 2 to discharge a refrigerant compressed by the compression section 3 to the outside of the closed container 2, a refrigerant discharge part 462 for discharging the refrigerant compressed by the compression section 3 toward the inner peripheral surface of the closed container 2 is provided, and a discharge temperature sensor 20 for detecting the discharge temperature of compressed refrigerant is arranged in a portion opposed to the refrigerant discharge part 462 on the outer peripheral surface side of the closed container 2.
