PURPOSE: To provide a superconductive coil which has high mechanical strength and resists electromagnetic force by improving rigidity of a double pancake winding coil. CONSTITUTION: Insulation is performed for a conductor 4 wherein a plurality of superconductive wires are contained inside a conduit and the conductor is wound in a plurality of turns in two layers to form a double pancake coil 1. In a superconductive coil wherein the double pancake coil 1 is laminated is provided with a non-adhesive insulation sheet 8 between turns of the conductor 4 and with an adhesive insulation sheet between layers of the conductor 4. In the non-adhesive insulation sheet 8 inserted between turns, resin flows out little due to heat setting; therefore, tension between turns is held and rigidity of a superconductive coil is improved. Furthermore, since an adhesive insulation sheet is inserted between layers, heat setting is possible while press is applied and rigidity of a superconductive coil can be further improved. |
