PROBLEM TO BE SOLVED: To provide a vacuum heat insulation container capable of preventing its shape from being deformed into an indefinite shape even if the container is exposed under a high temperature for a predetermined period of time, wherein its size is compact and a heat insulation performance can remarkably be improved. SOLUTION: There are provided an inner container 11 having a first opening 15 opened at one end, an outer container 12 arranged by a predetermined space from the inner container 11 to enclose it and having a second opening 21 opened at one end and fixed to the outer surface of the first opening 15, a heat-proof core material 37 arranged at either the outer surface of the inner container 11 or the inner surface of the outer container 12 and having a clearance between the inner surface of the outer container 12 or the outer surface of the inner container 11, and a sealing part 28 arranged at either the inner container 11 or the outer container 12, vacuum evacuating an inner space 43 between the inner container 11 and the outer container 12 to make a vacuum space and thereafter sealed. It is possible to prevent the container from being deformed into an indefinite shape even if it is exposed under a high temperature for a prdetermined period of time, its size is compact and it is further possible to improve remarkably its heat insulation performance.
