PROBLEM TO BE SOLVED: To provide a suctioned air rectifier capable of suppressing occurrence of condensed water to avoid failure derived from the condensed water.SOLUTION: An internal combustion engine 1 including an exhaust gas recirculation passage 26 connected to a downstream side of a throttle valve 35 installed in a suctioned air passage 10 is configured such that a suctioned air rectifier 50 of the internal combustion engine arranged on the downstream side of the throttle valve and configured to rectify suctioned air, includes a stationary annular part 51 arranged closely to an inner peripheral wall of the suctioned air passage, and a rectification part 52 disposed in the stationary annular part. A surface of the rectification part has super-water repellency.SELECTED DRAWING: Figure 2 【課題】凝結水の発生を抑制して凝結水由来の不具合を回避する内燃機関の吸気整流装置を提供する。【解決手段】吸気通路１０に設置されたスロットル弁３５の下流側に接続される排ガス再循環通路２６を備えた内燃機関１において、前記スロットル弁の下流側に配置されて吸気を整流する内燃機関の吸気整流装置５０であって、前記吸気通路の内周壁に近接して配置される環状の固定環状部５１と、該固定環状部内に配設された整流部５２とを備え、前記整流部の表面は、超撥水性を有する。【選択図】図２
