An intake manifold which is made of resin and configured to be connected to an intake port of a cylinder of an internal combustion engine, includes: an EGR inlet for discharging exhaust recirculation gas toward a cylinder side; and a tumble control valve which is switchable between an open position in which an intake line to the cylinder is opened and a close position in which the intake line is closed, and has an indentation that forms a gap between the tumble control valve and an inner wall of the intake line when the tumble control valve is in the close position. The intake manifold is configured so that, in the open position and in the close position of the tumble control valve, the EGR inlet and the tumble control valve do not overlap each other in a horizontal projection plane, and at the same time, in at least one of the open position and the close position of the tumble control valve, a most upstream portion of the EGR inlet in an intake direction is located within the indentation in the horizontal projection plane. |
