A casting device includes: a split mold for forming a cavity, including a lower mold, a middle mold that slides in a horizontal direction on the lower mold and an upper mold; a split case for forming a chamber, including a lower case to which the lower mold is attached and an upper case to which the upper mold is attached; a chamber suction device that reduces a pressure at least in the chamber through a chamber pipe that is connected to the chamber and extends to an outside of the chamber; and a cavity suction device that reduces a pressure in the cavity through a cavity pipe that is connected to the cavity and extends to the outside of the chamber. The cavity and the chamber are formed when the middle mold is closed on the lower mold and the split case is closed.
