<p><P>PROBLEM TO BE SOLVED: To provide a superconducting coil having excellent characteristics by helically winding the coil around a winding frame without distorting a tape-like superconducting wire. <P>SOLUTION: The superconducting wire 20 of the superconducting coil 1 includes a first winding part 21 helically wound around the winding frame 10 just one time so as to be shifted by one pitch in the axial direction in one rotation; a second winding part 22 which is continuous with one end 21a in a longitudinal direction of the first winding part 21 and wound concentrically around a one region 11A in axial direction of the winding frame 10; and a third winding part 23 which is continuous with other part 21b in a longitudinal direction of the first winding part 21 and wound concentrically around an other region 11B in the axial direction of the winding frame 10. The winding frame 10 has a shape capable of holding the first winding part 21 while being tilted relative to a cylindrical surface such that the strain generated in the first winding part 21 is reduced, in comparison with when the first winding part is closely wound around the cylindrical surface with a shaft center R of the winding frame 10 as the center. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
