Abstract

PURPOSE:To improve workability by mounting coils for induction heating on the outer circumference of a switch proper, on which a wire is wound and which is thermally treated. CONSTITUTION:A spool 1 on which a superconductive wire 3 and a heater 4 are wound is thermally treated, the outer diameter side of the spool is covered with a metallic cylinder 7 of the same kind as the spool 1, and the metallic cylinder is joined electrically with the spool 1. A coil wire 6 for induction heating is wound on the outer circumference of the metallic cylinder. The upper section of the coil wire is thermally insulated. The coil for induction heating may be mounted on the inner diameter side of the spool 1. The outer cylinder 7 is unnecessitated at that time. Accordingly, winding work is simplified, and workability is improved.
