Claims

[Scope of utility model registration request]

An exhaust manifold in which a cooling passage extending around the exhaust gas outlet of the exhaust manifold is formed in the exhaust manifold, and a cooling medium inflow hole and a cooling medium outflow hole communicating with the cooling passage are formed on the outer wall surface of the exhaust manifold. A core for a cooling passage, wherein the core is integral with a portion forming the cooling passage, a cooling medium inflow hole, and a cooling medium outflow hole, and a portion forming the cooling medium inflow hole and the cooling medium outflow hole. A core for a cooling passage of an exhaust manifold, comprising a core support portion formed in the core.
