ABSTRACT:
Disclosed herein is a multifilament superconducting wire of Nb.sub.3 Al comprising a core part of copper or copper alloy which is provided in a central portion as a stabilizing material and a peripheral part which is provided around the core part and formed by an Nb.sub.3 Al filament embedded in a matrix of copper or copper alloy, such that the ratio of copper or copper alloy forming the core part and the peripheral part to the Nb.sub.3 Al filament is at least 1 and not more than 5 in sectional area ratio and the diameter of the core part is at least 1/5 of the wire diameter.
