Abstract
An insulation-coated compound superconducting wire includes a compound superconducting wire having a compound superconducting part which includes a first matrix and a plurality of compound superconducting filaments containing compound superconducting phases, a reinforcing part disposed on the outer circumferential side of the compound superconducting part and includes a plurality of reinforced filaments, a second matrix and a second stabilizing material. A stabilizing part is disposed on at least one side among the inner circumferential side and the outer circumferential side of the reinforcing part. An electrical insulation part covers the outer circumferential surface of the compound superconducting wire, in which the insulation-coated compound superconducting wire has a critical current value (Ic) larger than that of the compound superconducting wire before being covered with the electrical insulation part.
