A vehicular heat management device includes a first heat source (21), a second heat source (23), a heater core (24), a first heat medium pathway (30), a second heat medium pathway (31), a heater core pathway (32), a switching portion (27, 28), and a control unit (60). The first heat source is provided in the first heat medium pathway, and the second heat source is provided in the second heat medium pathway. The heater core is provided in the heater core pathway through which a heat medium flows. The switching portion switches between flowing connection and flowing disconnection between the first heat medium pathway and the heater core pathway, and switches between flowing connection and flowing disconnection between the second heat medium pathway and the heater core pathway. The control unit performs at least one of a switching control and a second heat source control when a temperature of the heat medium of the heater core pathway is at or above a predetermined temperature. In the switching control, the control unit controls an operation of the switching portion such that the second heat medium pathway communicates with the heater core pathway. In the second heat source control, the control unit makes the second heat source generate heat.
