PROBLEM TO BE SOLVED: To provide a casting method by the gravity casting of a permeable casting mold, in which molten metal is filled only in a desired cavity part for filling the molten metal as a part of total cavities of the permeable casting mold, and its filling process is rapidly completed. SOLUTION: In the casting method, molten metal having the volume substantially equal to that of a desired cavity part for filling the molten metal is filled, additive materials are fed from a pouring gate, the poured molten metal is filled in the desired cavity part, and the additive materials are filled in other cavities.
