PURPOSE:To obtain a superconductive device firmly supporting superconductive wires in spool grooves and sufficiently enduring powerful electromagnetic force by a method wherein continuous grooves are provided in the circumference direction of round spools and superconductive wires surrounded by refrigerant paths through a plurality of spacers are wound in the circumference direction. CONSTITUTION:A plurality of continuous endless-shaped grooves 1a having predetermined intervals in the diameter direction are provided in the circumference direction of each spool 1 and a plurality of superconductive wires 2 are wound in the grooves 1a while supporting the superconductive wires 2 by penetrating spacers 4 provided with predetermined intervals in the circumference direction. Refrigerant paths 7 surrounding the superconductive wires 2 and flowing superconductive heliun are provided at the outside circumference of the superconductive wires 2 and stack bolts 6 are provided at the outside circumference end sections of the spools 1. In this composition, covers 3 are arranged on the upper and lower plane sections of the spools 1 and the covers 3 are fixed by welding sections 5 by an electron beam. This transfers electromagnetic force generated on the superconductive wires 2 to the spools 1 through spacers 4 and prevents the deformation of the superconductive wires 2 with the aid of the spools 1. |
