PROBLEM TO BE SOLVED: To provide a vacuum magnetic shield container capable of surely keeping the container inside in a vacuum state without influenced by the differential pressure between the atmospheric pressure at an inexpensive cost. ! SOLUTION: An inside container 2 and an outside container 3 whose vacuum container 1 is formed separately from them are made to have a double structure and rigidity of the whole container is secured by overlapping and installing both inside and outside containers 2, 3 to configure a peripheral side parts of the vacuum container 1. The surface treatment after assembly is made unnecessary by forming the inside container 2 using a steel product not requiring rustproof treatment, and the inside of the vacuum container 1 is magnetically shielded by forming the outside container 3 using a magnetic steel product. !
