PROBLEM TO BE SOLVED: To provide a technique for surely supporting a turbocharger, preventing lowering in temperature of exhaust, and absorbing elongation of a pipe caused by heat, in exhaust manifold structure having an exhaust manifold with a part of branch pipes integrally molded with flanges by casting and the other branch pipes constituted of pipes, and having the turbocharger. SOLUTION: The exhaust manifold structure 1 has the exhaust manifold 5 and the turbocharger 7. The exhaust manifold 5 comprises: an upstream flange 11; first to forth branch pipes 13, 15, 17, 19; an exhaust aggregation case part 21; a pipe connecting part 23; a downstream flange 25; and a secondary air passage part 27. The upstream flange 11, the third and forth branch pipe 17, 19, the exhaust aggregation case part 21, the pipe connecting part 23, the downstream flange 25, and the secondary air passage part 27 are integrally molded by casting.
