    Abstract: An exhaust gas recirculation (EGR) device includes an EGR passage, a cooling medium circuit, an EGR cooler, and an intercooler. A part of exhaust gas flowing through an exhaust passage of an internal combustion engine is recirculated as EGR gas into an intake passage of the engine through the EGR passage. A cooling medium flows through the cooling medium circuit. The EGR cooler performs a heat exchange between EGR gas flowing through the EGR passage and the cooling medium flowing through the cooling medium circuit so as to cool EGR gas. The intercooler is disposed at the intake passage on a downstream side of a merging part between the intake passage and the EGR passage in a flow direction of intake air, and performs a heat exchange between intake air including EGR gas and flowing through the intake passage, and the cooling medium flowing through the cooling medium circuit so as to cool intake air.
