PURPOSE:To prevent a cooling channel from being sealed with resin by forming the cooling channel through hole opening after thermosetting resin is impregnated to superconductive wires and hardened. CONSTITUTION:A superconductive wire 5 is wound around a winding drum 1, after which thermosetting resin is impregnated to the superconductive wire 5 and hardened. Then, a cooling channel 10 for a spacer and a cooling channel 11 for a winding drum are formed by hole opening. As a result, channels are reliably formed without being sealed with resin. |
