PROBLEM TO BE SOLVED: To provide an intake manifold capable of suppressing the occurrence of warping in a manifold body when a valve case is welded onto the manifold body.SOLUTION: A valve case 16 of a flow control valve 15 is welded to the end on the downstream side of a manifold body 11. In the valve case 16 of the flow control valve 15, two flow paths 18 and 19 are formed and a valve plate 21 is provided for opening/closing at least one flow path 18. There is a level difference 25 on a joint area between the manifold body 11 and the valve case 16 so as to be higher at the side of the flow path 18 having the valve plate 21. |
