摘要：
A supercharged internal combustion engine according to the present invention includes a compressor 16a that supercharges intake air; an EGR passage 22 that connects an intake passage 12 at the upstream side of the compressor 16a and an exhaust passage 14; an EGR valve 26 that is provided in the EGR passage 22 and regulates the flow rate of EGR gas that flows through the EGR passage 22 by opening and closing the EGR passage 22; and a heat insulator 30 that is provided on a surface of the EGR valve 26 that is exposed to the EGR passage 22 which is located at the upstream side in the EGR gas flow with respect to a seal portion by a seal surface 26a1 and a valve seat 28a when the EGR valve 26 is in the fully closed position.
