PURPOSE: To enable a stable superconducting state always be maintained as well as to reduce the manufacturing cost by winding a superconducting wire while applying a solventless bonding agent thereon, and then hardening the bonding agent, thereby eliminating wire movement.
CONSTITUTION: After a case 7 is threaded with a superconducting wire 1, it is filled with a heat curing or cold curing bonding agent 6, and the superconducting wire 1 is caused to pass therethrough. At this time, the bonding agent 6 is applied on the superconducting wire surface. And, after the superconducting wire 1 is wound predetermined times while it is coated with the bonding agent 6, by hardening the bonding agent by heating or leaving it to stand at a normal temperature, the superconducting wires are bonded together and the superconducting wires 1 are integrated together, Then, no gap occurs between the superconducting wires 1, and no wire movement due to the electromagnetic force at the time of the magnet excitation occurs which causes quenching. Therefore, the superconducting magnet can maintain a stable superconducting state.
