PROBLEM TO BE SOLVED: To easily prevent product quality from being worsened by a fusible-salt adhesion to a cavity mold face in casting using a fusible-salt core. SOLUTION: A casting mold is equipped with a fusible-salt core, which is water-soluble and a part of which can be fused in casting. In the casting mold, a lower mold (a lower slide mold 4) has a water reservoir 46 in an adhesion part of a lower mold face 42, to which fused matter of the fusible-salt core may adhere. An adhering matter 5a of the fusible-salt adhering to the adhesion part is immersed in the water reservoir 46 by supplying water. The water reservoir 46 is formed by a bank-like part 45, which is provided in the lower mold so as to enclose the adhesion part. The adherent matter 5a of the fusible-salt is dissolved in the water in the water reservoir 46, whose temperature is raised, and then the water in the water reservoir 46 is removed by air blow or the like, so that the adherent matter 5a of the fusible-salt is easily removed.
