PROBLEM TO BE SOLVED: To provide an air conditioner for rapidly detecting leakage of a refrigerant with high accuracy. SOLUTION: A control device operates an indoor unit and an outdoor unit, inputs control values of an indoor fan, compressor, and an outdoor fan at this time, stores detected refrigerant temperatures of respective temperature sensors of the indoor unit and outdoor unit, and detected outside air temperatures of second and sixth temperature sensors as initial learning data, corrects refrigerant leakage detecting operation data used at a time of refrigerant leakage detection previously set in response to individual differences and actual installation conditions of respective equipment of the indoor unit and outdoor unit on the basis of the initial learning data, operates the indoor unit and outdoor unit so as to accumulate the refrigerant in the outdoor heat exchanger on the basis of the corrected refrigerant leakage detecting operation data, obtains a difference by inputting a detected temperature of the fourth temperature sensor and a detected temperature of the fifth temperature sensor at this operation time, determines whether the temperature difference is more than a previously set threshold value or not, and determines as refrigerant leakage when the temperature difference is more than the threshold value.
