なわれている。[Technical background of the invention] Conventionally, a high magnetic field magnet manufactured by using a compound superconducting wire by a wind & react method has been known, and in such a magnet, the superconducting characteristics are deteriorated due to an excessive hoop stress generated by an electromagnetic force. To prevent this, high-strength stainless wire or aluminum wire with high heat shrinkage is wound with high tension on the outermost layer of the coil part, or a cylinder made of stainless steel or aluminum is fitted and the coil is epoxy-coated. Impregnation with a resin or the like is performed.
