The dewar, which is composed of the cooling bottom 12, the flange portion 13, the optical window 1, etc., must have a vacuum-tight structure. However, when used in a vacuum atmosphere such as outer space, or even on the ground, it is often possible to use a vacuum exhaust system, and in such environments (or usage conditions), the above vacuum-secure The need disappears. The present invention focuses on this point, eliminates the cooling bottom, and creates a structure in which the package 3 is brought into direct contact with the thermal contact portion 8, thereby making it possible to reduce the heat capacity.
