A vehicular air-conditioning device includes a first water-refrigerant heat exchanger and a second water-refrigerant heat exchanger. The first water-refrigerant heat exchanger exchanges heat between a refrigerant of low-temperature and low-pressure and a heat transfer coolant to vaporize the refrigerant. The second water-refrigerant heat exchanger exchanges heat between the refrigerant of high-temperature and high-pressure and the coolant to condense the refrigerant. The coolant circulates through one of the first water-refrigerant heat exchanger and the second water-refrigerant heat exchanger, the other of the first water-refrigerant heat exchanger and the second water-refrigerant heat exchanger, a cooling path for cooling a heat generating component of a vehicle, and a heater core for heating air supplied to a vehicle interior in this order.
