A vehicular heat exchange device includes: a first medium flow circuit (61) through which a heat exchange medium that exchanges heat with an internal combustion engine (1) flows; a second medium flow circuit (62) through which the heat exchange medium that exchanges heat with an electric power storage unit (3) that can be charged and discharged flows; and a first valve portion (71, 72, 73, 74) switching between a communication state and a non-communication state between the first medium flow circuit and the second medium flow circuit, in which the vehicular heat exchange device is configured such that the first valve portion causes the first medium flow circuit and the second medium flow circuit to be in the communication state to raise a temperature of the internal combustion engine before driving of the internal combustion engine using heat of the electric power storage unit.
