<p>PROBLEM TO BE SOLVED: To provide a steady reinforcement structure for a thermally insulated panel, having a reinforced structure, and to maintain heat insulating effect for a long time. SOLUTION: The heat insulating panel according to the present invention has a built-in vacuum heat insulating material 50 and sandwiches a heat insulating member, whose cavity is filled with heat insulating parts 15, 17, such as a styrene slab material, an urethane foam slab material, an injection urethane foam material, by surface materials 11, 13. In addition, a reinforcement member 30 is arranged between one of the surface materials 13 and the vacuum heat- insulating material 50 so as to form a sandwiched panel structure, in which the heat-insulating part 17 is pinched between the reinforcement member 30 and the surface material 13, on one side (load side) of the vacuum heat insulating material 50.</p> |
