Abstract
In a coated high-temperature superconducting wire 1 in which a superconducting yttrium-based wire (high-temperature superconducting wire) 2 having a rectangular cross section is coated by an insulating layer 6, the insulating layer 6 is an electrodeposited film made of block copolymerized polyimide which contains siloxane bonds in a polyimide main chain and which has molecules with anionic groups. A coil formed from the superconducting yttrium-based wire 2 is impregnated with epoxy resin, and the epoxy resin is cured. The coil is configured such that the epoxy resin is completely separated from the superconducting yttrium-based wire 2 by the insulating layer 6.
