A first intake passage connected to a combustion chamber of the internal combustion engine via a helical port, and a second intake passage for intake swirl control connected to the first intake passage, wherein the first intake passage is connected to the combustion chamber of the internal combustion engine. The second intake passage is configured as an inertial intake passage whose length and passage cross-sectional area are set so as to exhibit an inertial effect in the low rotational speed range, and the intake port of the second intake passage is connected to the first intake passage. An intake passage structure for an internal combustion engine, characterized in that the intake passage is connected to the upstream side.
