<p>PROBLEM TO BE SOLVED: To provide a heat insulating panel capable of improving workability while suppressing deterioration of heat insulating performance.SOLUTION: A heat insulating panel 10 includes a flat plate-shaped panel body 20, and a heat insulating body 30 sealed inside the panel body 20, and the heat insulating body 30 is formed by filling a plurality of heat insulating containers 40 having a core material S made of a low heat conductive material in the panel body 20. The heat insulating container 40 is preferably evacuated by reducing inside pressure. The heat insulating container 40 is preferably spherical. Further, a ratio of an outside diameter D1 of the heat insulating container 40 with respect to a thickness L of the panel body 20 is preferably 0.46 or less.</p> |
