PROBLEM TO BE SOLVED: To prevent generation of radiation sound by suppressing vibrations of a branch pipe and suppressing vibrations of a stay itself. SOLUTION: In an intake manifold in which a stay 5 connects a plurality of branch pipes 2, 2, the stay 5 is composed of two stretching members 6, 7 which are closely overlaid. On the edges of the outside stretching member 6 and the inside stretching member 7, joint ends 6a, 6b, 7a secured to the outer periphery of the branch pipes 2, 2 by brazing or the like are formed.
