A mold for manufacturing car induction manifold having a lower mold(4) and an upper mold(5) wherein the molding surfaces(7A-1,7B-1) of manifold branch pipe are downward and the molding surfaces(7A-2,7B-2) of manifold main pipe are upward. But said surfaces(7A-1,7B-1,7A-2,7B-2) are inclined in about 25~35= to horizontal state of the mold. A port medium piece is inserted in the same degree as the inclined degree of said surfaces(7A-1,7B-1,7A-2,7B-2). Thereby, it is possible to increase productivity due to reduction of the number of medium, and to reduce manhour.
