[Scope of utility model registration request]

In a box-type water-cooled exhaust manifold for an internal combustion engine, two cooling water passages are formed that extend in the longitudinal direction through a partition plate 5 inside the pipe, and the two passages are connected so that the cooling water can reciprocate inside the pipe. Features a two-layer water-cooled exhaust manifold.
