As shown in FIGS. 2 and 3, the heat insulation panel 1
Reference numeral 7 is composed of a panel body 18 made of stainless steel and a heat insulating material 19 such as expanded polystyrene. The panel main body 18 has a central portion excluding both side edges thereof which bulges toward the front surface in an arc-shaped cross section to form a bulging portion 20, and a rear surface thereof is a recess 21. A web 22 and a rib 23 are formed on both side edges of the panel body 18. Therefore, the heat insulation panel 17 can be self-supporting. Therefore, when constructing a tank using this heat insulation panel 17, the heat insulation panel 17 is used.
Since it can stand by itself, its construction is easy. The labor can be reduced.

A heat insulating material 19 is housed in the recess 21 and is fixed to the inner surface of the recess 21 with an adhesive.
