PROBLEM TO BE SOLVED: To suppress reheating of intake air after passed through an intercooler by an intake pipe. SOLUTION: Heat transfer from a cylinder head 11 to an intake manifold 22 is suppressed by a heat-insulating means 50 arranged between the cylinder head 11 and the intake manifold 22, thereby suppressing a rise in temperature of the intake manifold 22. The intake manifold 22 is cooled by cooling water circulating in the heat-insulating means 50, thereby further suppressing the rise in the temperature of the intake manifold 22. Accordingly, a temperature difference between the intake manifold 22 and intake air is reduced, the intake air after passed through the intercooler 23 is less likely to be reheated, and an intake air cooling effect in the intercooler 23 is maintained.
