PROBLEM TO BE SOLVED: To provide a low-temperature tank capable of reducing an installation area and being inexpensively built. SOLUTION: This low-temperature tank 1 capable of storing a low- temperature liquefied gas is composed of an inner tank 40 capable of reserving the low-temperature liquefied gas, an outer tank 30 surrounding the inner tank, and a partition 10 capable of defining the clearance between the inner tank and the outer tank into an upper space and a lower space. The lower space has a height sufficient to reserve the low-temperature liquefied gas when the inner tank is broken. Further, the lower space has a gas discharger for discharging the gas in the lower space to the external, when the low-temperature liquefied gas is leaked to the lower space.
