A double-shell tank that stores a low temperature liquid includes: an inner shell having a non-spherical hollow shell shape and including therein a storing portion; an outer shell that covers the inner shell; and powdered thermal insulation that is filled in a space surrounded by an outer wall of the inner shell and an inner wall of the outer shell to become a heat insulating layer. Then, a size of a top portion gap between the inner shell in an empty state and the outer shell is larger than a size of a bottom portion gap between the inner shell and the outer shell. A thickness of the powdered thermal insulation of the top portion gap in the empty state is larger than the size of the bottom portion gap.
