PROBLEM TO BE SOLVED: To provide an exhaust manifold collective part structure capable of improving reliability in strength and ensuring the strength of the collective part. SOLUTION: In this structure, an exhaust manifold 10 welded with a plurality of pipes 6, 7, 8, 9 is inserted into a collecting pipe 11 and indirectly welded thereto through an intermediate member 27. The pipes 6, 7, 8, 9 are inserted in and welded to the intermediate member 27, then the intermediate member 27 is inserted in the collecting pipe 11 and welded upstream from the downstream end of the collective part, thus alleviating thermal stress exerted to the welded part of the collective part.
