PROBLEM TO BE SOLVED: To provide an air conditioner capable of keeping a proper overcooling degree. SOLUTION: This air conditioner for conditioning the air in a room by circulating a refrigerant compressed by a compressor 1 between an indoor heat exchanger 6 and an outdoor heat exchanger 20, comprises an electronic expansion valve 33 for throttling a part of the refrigerant from the outdoor heat exchanger 20, an overcooling heat exchanger 17 for cooling the refrigerant from the outdoor heat exchanger by the throttle refrigerant, a pressure meter (pressure detecting means) 31 for detecting an inlet-side refrigerant pressure of the compressor 1, a thermistor (temperature detecting means) 30 for detecting an inlet-side refrigerant temperature of the compressor 1, and a control part 35 for controlling the electronic expansion valve 33 on the basis of the detection outputs of the pressure meter 31 and the thermistor 30 to control the overcooling degree in the overcooling heat exchanger 17.
