PROBLEM TO BE SOLVED: To provide a hybrid type superconducting coil wherein an outer diameter of the entire coil can be miniaturized, exothermic caused by eddy current at magnetization is suppressed and electromagnetic force can be supported, without deforming a coil bobbin even when used for a refrigerator conducting cooling type superconducting magnet device, and requiring no reinforcing winding for an inner coil. SOLUTION: In a superconducting magnet, outer coil bobbins 3 and 3', made into a half, are tightly stuck to the outer surface of an inner coil 2 which is constituted in such a way that a compound based superconducting wire is wound around an inner coil bobbin 1, and a superconducting wire which comprises an NbTi material is wound on the outer coil bobbins 3 and 3' while tension is applied, to form an outer coil 4, and the inner coil 2 is press-held with the outer coil bobbins 3 and 3'. |
