An intake manifold is described for an internal combustion engine equipped with an exhaust gas recirculation system for introducing a part of the exhaust from an exhaust gas passage through an EGR pipe into an intake manifold. The intake manifold is provided with an EGR gas outlet port opened thereto and connected to the EGR pipe, and is also provided with a rib formed on and extending along an inner wall of the intake manifold at a position upstream of the EGR gas outlet. This is done in such a manner that the rib is obliquely extended with respect to an air flow direction so as to guide oil flowing downward along the inner wall away from the EGR gas outlet port.
