<p>PROBLEM TO BE SOLVED: To provide a heat insulation body which can cover a heat insulation object assuming a spherical shape and is excellent in heat insulation property.SOLUTION: A heat insulation body is formed by preparing a number of vacuum heat insulation panels 13A, 13B assuming a triangle shape in which a space between first and second panel members arranged opposite to each other is evacuated and connecting respective vacuum heat insulation panels 13A, 13B. Concretely, a first vacuum heat insulation panel 13A assuming a regular triangular shape in which sizes of a first edge to a third edge are equal to one another, and a second vacuum heat insulation panel 13B in which sizes of the first edge and the second edge, among the first edge to the third edge, are equal to each other, a third edge isosceles triangle is formed and the third edge or the first and the second edges have sizes equal to the sizes of the first vacuum heat insulation panel 13A are provided.</p> |
