PROBLEM TO BE SOLVED: To provide a collecting part structure for an exhaust manifold capable of reducing the exhaust gas interference of branch pipes without using partition plates. SOLUTION: In the collecting part structure for the exhaust manifold 1 provided with the branch pipes 3-6 communicating with and connected to corresponding exhaust ports E1-E4 of an engine E, and a collecting part 7 collecting and storing exhaust downstream side ends 3b-6b of the branch pipes 3-6, projection lengths of exhaust downstream side ends 4b, 5b of the branch pipe 4, 5 into the collecting part 7 are different from those of the branch pipes 3, 6.
