PURPOSE: A casting product manufacturing method is provided to facilitate heat radiation of a metal melt which is injected into the inner space of a molding material, thereby preventing the thickness of an interfacial reaction layer from becoming thicker. CONSTITUTION: A casting product manufacturing method comprises the following steps. A mold layer including ceramics is coated on a wax pattern after the wax pattern is made. A backup layer which includes metal oxide is coated on the mold layer. A mold material is manufactured by heat-treating the mold layer and the backup layer in the reducing atmosphere after the wax pattern is removed. A metal melt is injected in the mold material. The metal oxide comprises copper oxide.
