Abstract
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 externl 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 sizes of various shapes, and by combining them variously with each other leaving spaces betwen them, magnetic inductions are made to generate in the high permeability members, and a penetrating magnetic field is made to be shorted magnetically.
