Zusammenfassung:	PURPOSE:To prevent a manifold from an excessive rise of its temperature and extend a durable life, by providing a heat insulating layer, solidifying a fire-resistant heat insulating material consisting of inorganic fiber, in an internal surface of the cast iron made manifold while a fire-resistant layer, solidifying a fire-resistant dust, in the surface of said heat insulating layer. CONSTITUTION:A cast iron made manifold provides a heat insulating layer, solidifying a fire-resistant heat insulating material consisting of inorganic fiber, on an internal surface of the manifold further a fire-resistant layer, solidifying a fire-resistant material dust, on the surface of said heat insulating layer. Here the fire-resistant heat insulating material, used for giving a heat insulating property, uses an inorganic fiber of ceramic fiber or the like. While the fire- resistant material preferably uses, for instance, zirconia or the like with low heat conductivity. In this way, the fire-resistant heat insulating layer, being provided between the fire-resistant layer and the manifold, prevents the manifold from being heated to a temperature exceeding 600 deg.C even for the passing of exhaust gas at a temperature exceeding, for instance, 1,000 deg.C, and a durable life can be substantially extended.
