PROBLEM TO BE SOLVED: To provide an air conditioner for a vehicle capable of suppressing a rise of a cooling temperature in a cabin with a simple constitution when a compressor is stopped according to stopping of a vehicle engine. SOLUTION: When the vehicle engine 3 is stopped during an idle stop, an air flow introduced by an air blowing fan 14 evaporates water droplets dew-condensed in an evaporator 8, the air flow is made to flow out, while increasing humidity, and the air flow is made to flow into a cooling device 17. A heat absorbing material 18 of the cooling device 17 reacts by being contact with moisture contained in the air flow to generate a heat absorbing action. The air flow therefore becomes cold air and is blown to the inside of a cabin, to suppress a rise of a cooling temperature in the cabin. Supply of cold air into the cabin is continued till all of the heat absorbing materials 18 are dissolved, and thereby a cooling environment in the cabin is supplemented for fixed time after stopping of a cooling operation. The dissolved heat absorbing material 18 is dried by cold air dehumidified during the cooling operation. The heat absorbing material 18 radiates heat during drying and all of the heat is used as evaporation heat of moisture to be evaporated, and thereby the heat absorbing material 18 can be reproduced without affecting the cooling operation.
