An air conditioner for a vehicle has a sunlight amount sensor for detecting the amount of sunlight incident into a vehicle, the other sensors and an air conditioning control device that controls the blowing out amount of the conditioned air at each blow-out port in association with the signals detected by the sensors. The air conditioning control device conditions the air by using the fixed amount of sunlight when the change in the amount of sunlight detected by the sunlight amount sensor is equal to or less than a predetermined value so that the air conditioning is performed comfortably for a passenger.
