An exhaust manifold in which a plurality of branch tubes at an inlet side are connected to a collecting tube at an outlet side, and in which the fluid flows from the branch tubes to the collecting tube, wherein a volumetric chamber is provided between at least a pair of the branch tubes in communication with the branch tubes, with the volumetric chamber being gradually increased in its cross-sectional area in a fluid flowing direction. An exhaust manifold formed of upper and lower members comprises a branch tube having a bend. The upper lower members are interconnected by joining flanges having a broader width in the vicinity of the bend than other joining flange portions.
