に、コイル加工が容易になる。As described above, the present invention is one in which a shielding layer made of a high-resistance conductive material is formed so as to surround the stabilizing base material, at least on the inner side of the outer casing that surrounds the stabilizing base material containing the superconducting element wires. Therefore, when a large current is applied to the superconducting wire of the present invention to generate a strong magnetic field, even if a change in the magnetic flux occurs during energization or fluctuation of the current, the shielding layer forms a coating between the jacket and the stabilizing base material. Suppresses the generation of coupling current between them. Therefore, the superconducting wire of the present invention has excellent characteristics such that the superconducting state is not easily broken and the superconducting property is stable, and that it is particularly suitable for a large size and high magnetic field magnet. Further, when the superconducting wire is coiled, it is necessary to bend the superconducting wire with a predetermined radius of curvature. In the case of such bending, the shielding layer is constituted by winding the tape around the outer periphery of the channel-shaped material, or by vertically arranging the tape on the outside of the stabilizing base material, Coil processing is facilitated because the abutted tapes are displaced from each other to facilitate deformation.
