PURPOSE:To effectively remove the influence of a magnetic field on an oxide superconducting lead which constitutes a part of a current lead. CONSTITUTION:A superconducting magnet device is provided with current leads 23a, 23b which supply a current to a super-conducting coil 9, and a part of the current leads 23a, 23b is composed of an oxide superconductor 25. In the super-conducting magnet device, the part which is formed of the oxide-based superconductor 25 is formed in such a way that the side of at least a high- temperature end 30 is arranged so as to make the direction of a current flowing to the side of the high-temperature end 30 nearly parallel to the direction of a leakage magnetic field applied to the side of the high-temperature end 30 from the superconducting coil 9. |
