PROBLEM TO BE SOLVED: To provide an air conditioner for a vehicle which prevents lubricating oil and refrigerants from being retained in either one of compressors even without providing a selector valve and a check valve to thereby increase the durable service life and the cooling performance of a compressor or an electric compressor. SOLUTION: The air conditioner for a vehicle is provided with the electric compressor 200 disposed in parallel to the compressor 111 and having a compressor part 220 that compresses the refrigerant through the driving of a motor 210, and a control device 130 controlling the operation of the electric compressor 200, wherein the electric compressor 200 is operated by the control device 130 when an engine 10 is stopped during the operation of the air conditioner 110. The electric compressor 200 is controlled so as to operate for a specified time T1 also when the compressor 111 is operated by the engine 10. Alternatively, the compressor 111 may serves as a variable displacement compressor 111a which controls displacement volume in the operation so as to be larger.
