PURPOSE: To enable sink marks to be less generated in a resin layer in the vicinity of the center of a coil-wound port and to manufacture a superconducting coil and a permanent current coil where quenching hardly occurs. CONSTITUTION: A superconducting coil 1 in a winding frame 3 is composed of a superconducting wire 2 which is wound in a coil and a thermosetting resin 5. When the resin 5 is cured by heating, a current is applied to a drying oven heater 10 by a temperature controller 8, and also a current is fed to a superconducting wire 2 from a direct current power supply 7. At this point, the set curing temperature of the resin 5a near the center of the resin 5 is set 1 to 10 deg.C higher than that of the peripheral resin 5b. By this setup, the center part 5a of the resin 5 is cured first, and then the peripheral part 5b is gradually cured, so that sink marks are less generated. |
