Abstract: A condensing portion is formed such that a first refrigerant flow path through which a gas-phase refrigerant flowing into a refrigerant inlet flows and a first heat-medium flow path through which a heat medium flows overlap each other in a stacking direction of plates. A gas-liquid separator separates the refrigerant into gas-phase refrigerant and liquid-phase refrigerant and discharges the liquid-phase refrigerant. A subcooling portion is disposed on one side in the stacking direction with respect to the condensing portion, is formed such that a second refrigerant flow path through which the liquid-phase refrigerant discharged from the gas-liquid separator flows toward a refrigerant outlet and a second heat-medium flow path through which the heat medium flows overlap each other in the stacking direction.
