PURPOSE:To prevent the short-circuit between a superconductive coil and a spool by mounting soft mica between the spool and the superconductive coil in which the superconductive conductor is made of compound material. CONSTITUTION:For example, plate-shaped soft mica 6 is arranged between a spool 2 and a superconductive coil 1 wound by a compound material superconductive conductor consisting of Nb3Sn or the like. In this way, a deterioration in characteristics as an electric insulating material will not occur even if heat treatment is applied to the coil 1 at about 900 deg.C, for example, and the short-circuit between the superconductive coil and the spool can be prevented. |
