In an air-conditioning apparatus of a so-called heat pump system, wasteful power consumption to be generated when an auxiliary heating means is disposed on an air upstream side of a radiator is decreased, and comfortable heating of a vehicle interior is also achieved. The air-conditioning apparatus includes an electric heater 57 disposed on an upstream side of air flowing through an air flow passage 3 to a radiator 4, and a controller executes a cooperative operation of heating air to be supplied to the vehicle interior by the electric heater 57 and the radiator 4, and stops a compressor 2 on the basis of establishment of a condition that an inlet refrigerant temperature Tcxin of the radiator is lower than an outlet refrigerant temperature TCI of the radiator (Tcxin
