An air conditioning device for a vehicle is provided with a refrigeration cycle (10), a heating unit (20), and a control unit (50). A refrigeration cycle is provided with a compressor (11), a condenser (12), an air-conditioning evaporator (15), a cooling evaporator (16), an air-conditioning-side flow path (17b), a bypass flow path (17c), and an air-conditioning flow rate adjustment unit (14a). The air-conditioning-side flow path is formed such that the refrigerant passes through the air-conditioning evaporator. The bypass flow path is formed so that the refrigerant bypasses the air-conditioning evaporator. The heating unit is disposed on the downstream side of the air-conditioning evaporator with respect to the flow of the blown air, and heats at least a portion of the blown air that has passed through the air-conditioning evaporator. The control unit has a determination unit (50a). Furthermore, when the determination unit determines that the condensation generation condition is satisfied, the control unit co
