The present invention pertains to a superconducting magnetic shielding device that can achieve high magnetic shielding even if a tape-shaped superconducting wire rod is used, and that has: a first axial-direction magnetic shielding having a first axial-direction superconducting material resulting from a tape-shaped superconducting material being formed into a ring shape a second axial-direction magnetic shielding having a second axial-direction superconducting material resulting from a tape-shaped superconducting material being formed into a ring shape and disposed in a manner so as to encircle the outer periphery of the first axial-direction superconducting material a transverse-direction magnetic shielding that is disposed perpendicular or inclined with respect to the axial direction of the first axial-direction magnetic shielding and second axial-direction magnetic shielding and that has a transverse-direction superconducting material that is electrically connected to the first axial-direction magnetic shielding and second axial-direction magnetic shielding and a support body that supports the first axial-direction magnetic shielding, second axial-direction magnetic shielding, and transverse-direction magnetic shielding. The configuration is such that the position of the end of the first axial-direction superconducting material and the position of the end of the second axial-direction superconducting material are caused to be different, and the outer peripheral surface of the first axial-direction superconducting material and the inner peripheral surface of the second axial-direction superconducting material are coupled by a conductive coupling material.La présente invention concerne un dispositif supraconducteur de protection contre les perturbations magnétiques qui permet dobtenir une haute protection contre les perturbations magnétiques même lorsquon utilise un fil métallique supraconducteur en forme de bande, ce dispositif comprenant : une première protection
