A method for producing ozone ice, wherein storage stability of ozone ice is improved. Specifically disclosed is a method wherein ice (11) containing an oxygen gas (g2) in the form of air bubbles (b) is produced and the thus-produced ice (11) is irradiated with ultraviolet light, so that the oxygen gas (g2) in the ice (11) is ozonized, thereby producing ozone ice (1). |
