摘要： An air conditioner employing a flammable refrigerant, comprises a sensor (11) that is provided on an external surface of an indoor unit (1) and detects the flammable refrigerant gas, in order to prevent the accident of a fire or the like even when the flammable refrigerant leaks. Furthermore, an air conditioner is provided with a indoor unit housing a heat exchanger (3) and a fan (7) inside its casing (2) that has an inlet port (8) and an outlet port (5). The air conditioner rotates the fan (7) and flows the flammable refrigerant through the heat exchanger (3) during operation, performing heat exchange between air taken into the casing (2) through the inlet port (8) and the flammable refrigerant, and blows out the air that has undergone the heat exchange to the inside of a room through the outlet port (5). The air conditioner comprises a sensor (11) that is provided on an external surface of the casing (2) and detects a flammable refrigerant gas and a control section (9) for executing control to rotate the fan (7) when the sensor (11) detects the flammable refrigerant gas.
