Provided is a double-structure low-temperature tank for storing a very low-temperature liquid therein. The structure is simple and easy to construct, and the low-temperature tank is very reliable while also having reduced construction costs. A double-structure, bottomed cylindrical low-temperature tank (100) comprising an inner tank (3) for storing a low-temperature liquefied fluid (L) therein, and an outer tank (6) which is provided outside the inner tank (3), wherein the inner tank (3) is provided with an inner vessel (1) made of concrete and an inner side cold-energy resistance easing layer (2) which covers the inner surface of the inner vessel (1), and the outer tank (6) which encloses the inner tank (3) is provided with an outer vessel (4) made of concrete and an outer side cold-energy resistance easing layer (5) which covers the inner surface of the outer vessel (4). |
