PURPOSE: An exhaust gas re-circulation device of an internal combustion engine is provided to prevent deterioration of fuel consumption ratio, to cut down cost of production, and to decrease the weight. CONSTITUTION: In a cylinder head(2) of an internal combustion engine, an intake port(4) for inflow of intake air and an exhaust port(6) for exhaust of exhaust gas burned are formed, and an intake valve(8) and an exhaust valve(10) are disposed at the ports. A weather jacket(18) is formed between the intake port and the exhaust port, and coolant is circulated. An exhaust gas re-circulation device of an internal combustion engine is equipped with an exhaust gas inflow device to lead some of the exhaust gas exhausted through the exhaust port to the intake port, in intake strokes.
