Abstract
An intake manifold is equipped with a sub-stream passage connected to branch passages through respective connection ports to introduce intake-air substream other than intake-air mainstream to the plural branch passages. Two of the branch passages which communicate with each other through the sub-stream passage and successively introduce intake air to the internal combustion engine are defined as a first combination. Of the first combinations, a second combination is defined to have a shortest communication length via the sub-stream passage. Of the second combination, the connection port of one of the branch passages where the intake air is introduced later is narrower than that of the other of the branch passages where the intake air is introduced earlier.
