Provided is a vehicular air conditioning device capable of heating the cabin interior with high efficiency even when the outside air temperature is low such that not much exhaust heat can be obtained from a heat generating component of a vehicle. The vehicular air conditioning device is provided with: a first water-refrigerant heat exchanger that vaporizes refrigerant by exchanging heat between the refrigerant of low temperature and low pressure in a heat pump and a cooling fluid for the heat generating component of the vehicle; and a second water-refrigerant heat exchanger that condenses the refrigerant by exchanging heat between the refrigerant of high temperature and high pressure in the heat pump and a cooling fluid for heat transport. The vehicular air conditioning device is configured such that the second water-refrigerant heat exchanger is connected, in a cooling fluid circulable manner, to a heater core for providing heat to air supplied into the cabin. The first water-refrigerant heat exchanger is connected, in a cooling fluid circulable manner, to a passageway for cooling the heat generating component without passing through the heater core.
