摘要： PURPOSE:To obtain a super-conductive magnet compact and stable, by a method wherein a super-conductive alloy coil is disposed through either one of or both of an insulating layer or/and a reinforcing layer on the outside of a super-conductive compound coil fixed by means of impregnating agents. CONSTITUTION:While a super-conductive wire of V3Ga compound is wound on a bobbin 11 made of glass epoxy resin, glass cloths are inserted and epoxy resins are applied between wound layers, and a super-conductive coil 12 of V3Ga compound impregnated with epoxy resin is fitted between wires and between layers. After that, while epoxy resin is applied as a reinforcing insulating layer 13 to the outer periphery of the coil 12, a glass cloth is wound thereon, then, epoxy resins within the coil 12 and within the reinforcing insulating layer 13 are heated and hardened. Thus hardened reinforcing insulating layer 13 is provided with a super-conductive coil 14 of NbTi thereon, and is provided with a reinforcing layer 15 further thereon.
