A magnetically shielding structure in which by combining magnetically shielding members of various qualities with each other, its magnetically shielding capability is made to improve, and the greatly lower magnetic field than an external one can be realized effectively. For this purpose, by providing a cylindrical magnetically shielding body made of a superconductive material manifesting Meissner effect and high permeability members of a predetermined size and various forms, and by combining them variously with each other leaving spaces between them, magnetic inductions are made to generate in the high permeability members, and a penetrating magnetic field is made to be shorted magnetically. <IMAGE> |
