This vehicular air-conditioning device is equipped with a cooling water circuit (23) for heating and heating devices (26, 44, 47, 48, 49). In the cooling water circuit for heating, cooling water is circulated between an engine (11) serving as the power source of a vehicle and a heater core (25) heating air using the heat of the cooling water of the engine. The heating devices are arranged downstream of the engine and upstream of the heater core in the cooling water circuit for heating , and heats the cooling water. Thus, it is possible to improve the fuel efficiency of the vehicle having a system equipped with the heater core that heats the air using the heat of the cooling water of the engine.
