PROBLEM TO BE SOLVED: To provide a heat-resistant container configured to prevent inside moisture from being discharged to the outside under a low-temperature environment, and to discharge inside vapor to the outside in a high-temperature environment, thereby preventing increase in internal pressure.SOLUTION: A heat-resistant container 10 includes: an inner container 11 for housing a temperature measurement instrument 20 which processes temperature measurement data; an outer container 12 for housing the inner container 11; and a heat-insulating material 13 which is filled between the inner container 11 and the outer container 12, and containing moisture. The outer container 12 has a depressurizing hole 12c which is a communication hole for allowing the inside and outside of the outer container 12 to communicate with each other. The depressurizing hole 12c is closed by a plug member 15 formed of a material having a thermal expansion coefficient lower than the outer container 12. |
