The temperature of an EGR gas is decreased rapidly. An EGR apparatus (30) for an internal combustion engine comprising an EGR passage which connects an exhaust passage and an intake passage of the internal combustion engine, and a part of an exhaust gas which flows through the exhaust passage is supplied to the intake passage as the EGR gas, wherein a part of the EGR passage (31C) is disposed to surround a part of the intake passage (22A). As the EGR passage (31C) surrounds the intake passage (22A), a heat exchange is made between an intake air and the EGR gas, so that the temperature of the EGR gas decreases. |
