description Provided are a casting die inspection method and a casting device, the method including: a step for acquiring the ultimate pressure in a cavity section, at the time when a prescribed vacuuming time has elapsed since evacuation the inside of the cavity section of the casting die was started; a step for evacuating the inside of the cavity section and acquiring an increased pressure in the cavity section that has increased during a prescribed stop time, at the time when the prescribed stop time has elapsed since the evacuation was stopped; a step for evaluating a first sealing property of the casting device on the basis of the ultimate pressure; and a step for evaluating a second sealing property of the casting device on the basis of the increased pressure.
