摘要： An intake apparatus of an internal combustion engine includes: an intake passage configured to communicate with a combustion chamber of an internal combustion engine having two intake valves per cylinder and supply intake air to the combustion chamber; and an intake flow control valve installed in the intake passage and configured to control a flow of intake air by an opening formed between a valve body and an inner surface of the intake passage when the valve is closed as the valve body is rotated, in which, when the intake flow control valve is closed, an opening length of the opening, which is formed on an end side in an arrangement direction of the two intake valves in a direction orthogonal to the arrangement direction and an intake air flow direction, is longer than an opening length of the opening, which is formed at a central portion of the intake flow control valve in the arrangement direction in the direction orthogonal to the arrangement direction and the intake air flow direction.
