A casting device in which refrigerant is pressure-fed to a cooling passage formed in a die, leakage of refrigerant in the die can be reliably detected in a short time without a significant modification applied to the conventional device. A casting device includes a pressure-feed device that pressure-feeds refrigerant to a cooling passage formed in a die, and a release agent coating applicator that applies a release agent to the die, and further includes a unit that mixes a fluorescent agent into the refrigerant (fluorescent agent tank), a unit that irradiates the die surface of the die with black light while the refrigerant containing the fluorescent agent mixed therein is pressure-fed to the die, and an imaging device that captures an image of the die surface. The imaging device is integrally assembled with the release agent coating applicator.
