PROBLEM TO BE SOLVED: To provide a liquefied gas storage device capable of stably controlling the liquid amount. SOLUTION: The liquefied gas storage device 15 comprises a storage vessel 2 to store liquefied gas, a low-pressure side pressure conduction pipe 8 in communication with a gas phase portion 3 of the storage vessel 2, a high-pressure side pressure conduction pipe 16 in communication with a liquid phase portion 4, a differential pressure gage 10 for measuring a differential pressure between the low-pressure side pressure conduction pipe 8 and the high-pressure side pressure conduction pipe 16, and an orifice 18 for preventing the liquid phase of the liquefied ozone from flowing into the high-pressure side pressure conduction pipe 16. The orifice 18 is disposed near a communication port 2f for communicating between the high-pressure side pressure conduction pipe 16 and the storage vessel 2. The liquid phase of the liquefied oxygen in the storage vessel 2 flows into the high-pressure side pressure conduction pipe 16 to absorb external heat, and is vaporized, so as to form a gas-liquid interface S.
