Summary:PROBLEM TO BE SOLVED: To prevent local vibration produced in a part having low rigidity in an intake manifold fixed to an engine. SOLUTION: A fixing structure for an intake manifold 10 includes a first mounting means 29 for fixing to a bracket 30 of an engine 12 a throttle body 16 of the intake manifold 10 equipped with a manifold body 14 distributing intake air to each of cylinders of the engine 12, and a second mounting means 39 for fixing a mounting flange 25 of the manifold body 14 to a cylinder head 40 of the engine 12. The first mounting means 29 generates bending moment in the manifold body 14 by a fixing force for fixing the throttle body 16 to the bracket 30. An angular difference θ is set between a first installation surface 35 of the bracket 30 and a first mounting surface 34 of the throttle body 16 in a free state of the intake manifold 10.
