PROBLEM TO BE SOLVED: To provide an intake device for improving combustion efficiency and emission, by restraining fuel sticking to an under surface of a partition plate. SOLUTION: This intake device 1A of an internal combustion engine has an intake control valve 20 for opening and closing a second intake passage, by dividing the inside into a first intake passage and the second intake passage, by arranging the partition plate 4 in the longitudinal direction in an intake pipe 3; and has a communicating part 25 for making a part of intake air GS turning to a combustion chamber flow along the partition plate on the second intake passage side, when the intake control valve 20 closes the second intake passage 6. The intake device 1A prevents sticking of the fuel FU to the partition plate 4 by a part SGS of an intake air flow flowing via the communicating part, and can improve combustion efficiency and emission of the internal combustion engine since the sticking fuel can be scraped away.
