As the carbonaceous granular heat insulating material 5, commonly used materials such as coke grains, carbon black molded grains, and Cryptol can be used, but granular materials made by forming and adhering glassy carbon to the surface layer of carbon black pellets can also be used. The body is ideal for the purpose of this invention, as it has a high degree of thermal insulation and a homogeneous spherical shape that is advantageous for handling. In particular, the homogeneous spherical shape improves fluidity, making it easier to carry in and out, and provides the ability to uniformly fill every corner of the compartment 7, regardless of the shape of the compartment 7, which varies depending on the design of the structure.
