PROBLEM TO BE SOLVED: To provide an exhaust manifold capable of protecting a catalyst holding material in good performance and being embodied at a low cost by means of lessening of the number of component parts. SOLUTION: The exhaust manifold 5 is to be joined with upstream of a catalyst case 1 fitted internally with a catalyst 2 whereon a catalyst holding material 3 is fitted, wherein a weir 5d for preventing the exhaust gas from direct bombardment is formed consolidatedly in such a way as preventing the exhaust gas from directly blowing to the upstream end of the catalyst holding material 3. |
