Abstract
It is an object of the present invention to provide an MgB2 wire helping to achieve compatibility between the ease with which superconducting connection is effected and thermal stability. A superconducting wire according to the present invention includes: an elemental wire formed of MgB2; and a first metal not reacting with Mg. In a section orthogonal to the longitudinal direction of the superconducting wire, the region extending from the center of the superconducting wire to the installation position of the elemental wire is formed by the elemental wire and the first metal.

to 13. (canceled)
A superconducting wire comprising:
- an elemental wire formed of MgB2;
- and a first metal not reacting with Mg,
- the superconducting wire further comprising:
- an inner peripheral portion situated at a central portion of the superconducting wire and formed by the elemental wire and the first metal;
- and
- an outer peripheral portion situated on an outer side of the inner peripheral portion and formed of a second metal which reacts with Mg,
- wherein the second metal is of higher hardness than the first metal.
