PROBLEM TO BE SOLVED: To provide an air conditioner capable of lessening affect by fluctuation of outside air temperature/humidity on control accuracy, by returning a part of the temperature-controlled air to an air suction opening, and to enlarge a range of conditions of usable outside air by lessening the affect by the fluctuation of outside air. SOLUTION: This air conditioner comprising a housing 3 provided with the air suction opening 1 and an air discharge opening 2, a cooling coil 4 disposed on the air suction opening 1, an electric heater 5 disposed at a downstream side of the cooling coil 4, and an air blower 6 discharging the air in the housing 3 from the air discharge opening 2, further comprises a bypass flow channel 7 taking a part of the air of which a temperature is conditioned by the cooling coil 4 and the electric heater 5 and returning the air to the air suction opening 1, and a bypass valve 8 for adjusting an opening of the bypass flow channel 7.
