PROBLEM TO BE SOLVED: To realize compatibility between securement of high output at the time of full-open performance of an engine and reduction in NOx emission amount by EGR gas injection and improvement of fuel economy at the time other than full-open performance. SOLUTION: This intake device for the internal combustion engine is equipped with an intake passage 2 vertically partitioned by a partition wall 7, EGR piping 11 communicating an exhaust passage of the engine with the intake passage and having an opening part 4 in the upstream side from the partition wall 7 of the intake passage 2, and an on-off valve 3 provided in the vicinity of an upstream side end part of the partition wall 7 and blocking the opening 4 of the EGR piping 11 at the time of full-open performance.
