An intake device of an internal combustion engine, comprising: a plurality of intake passages for introducing an intake gas into a row of engine cylinders, respectively; and a secondary gas passage for introducing a secondary gas into the intake passages, the secondary gas passage including a main gas channel to allow a flow of said secondary gas to be distributed to all of said engine cylinders, an adjacent gas channel extending downstream from the main gas channel adjacently and substantially in parallel with the mairf gas channel and across the intake passages to allow a flow of said secondary gas to be distributed to fewer than all of said engine cylinders, and branch gas channels branching off from the adjacent gas channel and continuing to the intake passages, the branch gas channels including a common branch gas channel connected to at least two of the intake passages and being branched at a position just before the connection of the common branch gas channel to said at least two of the intake passages.
