<p>PROBLEM TO BE SOLVED: To provide a vacuum heat insulation material excellent in heat insulation performance under various temperature environments, and a heat insulation container.SOLUTION: A vacuum heat insulation material 10 includes a substantially plate-like core material 11 and a sheath material 12 encapsulating the core material 11, and is formed by decompressing the inside of the sheath material 12. The core material 11 is configured by laminating at least a foam structure layer 111 having a foam structure comprising an organic material and a powder structure layer 112 being aggregate of powder structures comprising a clay mineral. Also, a heat insulation container is preferably disposed in such a manner that the foam structure layer 111 is on a low-temperature side and the powder structure layer 112 is on a high-temperature side.</p> |
