問題を有していた。Conventionally, in order to form a superconductor into a linear shape, the superconductor was filled into a metal pipe made of copper, silver, etc., and the metal pipe was drawn out through a die. However, in such a structure, when a ceramic such as an oxide superconductor with a high superconducting transition temperature is used, the bending of the linear body causes uneven stress in the internal superconductor within its cross section. Occur. This uneven stress causes the brittle superconductor to break and lose its properties as a superconductor. Therefore, when bending such a linear body, it is necessary to ensure an extremely large radius of curvature. There was a problem with its handling.
本発明の目的は、可とう性に優れた超伝導線及びその製

A conductor coating is provided on a superconductor strand consisting of a superconductor coated on the outer periphery of the superconductor wire.

4 is a linear conductor, and 5 is a conductor cylindrical covering. In FIG. 1, for example, a silver wire or a steel wire is effective as the linear conductor 4. Further, as the superconductor 3, it is effective to use a copper complex oxide (for example, Y-Ha-Cu type, Nd-Ba-Cu type, etc.) having a high superconducting transition temperature.

導体３の破壊が生じにくい。従って、本発明の超伝導線

とが容易であり、曲げに対する制限（許容曲げ半径）も
緩和できる。For example, silver or steel is effective as the conductor cylindrical coating 5. The role of the conductive cylindrical coating 5 is to improve mechanical strength and stabilize the superconducting state. In the superconducting wire 1 having such a structure, the superconductor 3 is coated on the linear conductor 4 to form the superconducting strand 2, so when the superconducting wire 1 is bent,
The difference between the compressive stress on the inner surface and the tensile stress on the outer surface of the superconductor 3 is smaller than in the case of a conventional superconductor housed in a metal pipe. Therefore, the superconductor 3, which is a brittle body, is less likely to be destroyed. Therefore, by using the superconducting wire 1 of the present invention, it is easy to twist them to form a cable, and the restrictions on bending (permissible bending radius) can be relaxed.
