PROBLEM TO BE SOLVED: To facilitate the manufacture of an oxide super-conducting coil of multi-layer structure, by comprising a plurality of unit coils wound with an oxide super-conducting wire material, and allowing the unit coils to comprise a spool while an end part of the oxide superconducting wire material is connected to a terminal on an insulating protruding part of the spool. SOLUTION: With an insulating recessed/protruding core formed as a spool, an upper step part and a lower step part provided with an insulating protruding part in between are wound with an upper coil and a lower coil, and a terminal of an oxide super-conducting wire material fixed to provide one unit coil group 9a and the other unit coil group 10a. A unit coil group 9a is provided at a bottom stage, the other unit coil group 12a is laminated over it, and further, another unit coil group 9a is laminated over it. A positive feeding terminal 28 from an external power source is jointed to an L-shaped terminal plate wherein a positive terminal 17a of the lower coil of the unit coil group 9a at the bottom stage is fixed, while a negative feeding terminal 30 is jointed and fixed to an upper-stage L-shaped terminal part 29 wherein the negative terminal of the unit coil group 9a at the upper stage is fixed. |
