PROBLEM TO BE SOLVED: To provide an intake module for an internal combustion engine formed in simple and various structures. SOLUTION: This intake module 1 generally comprises a plurality of intake passages 2, 3, 4, 5. Intake tube inflow holes 21, 22; 31, 32: 41, 42: 51, 52 are formed in these passages. The two intake pipe inflow holes belong to one intake passage so that the cross sectional areas of the first intake pipe inflow holes 21, 31, 51 of the intake passage are constant and the cross sectional areas of the second intake pipe inflow holes 22, 32, 42, 52 are made variable according to the operation mode of the engine. For this purpose, partition wall members 23, 33, 43, 53 dividing the intake passage itself at a specified portion are fitted into a housing 6 in which the intake passage is formed, and a movable member 7 making variable the cross sectional area of the second intake pipe inflow hole is installed on the partition wall member.
