ABSTRACT:
An aluminum-stabilized superconducting wire comprises an aluminum member, a copper member, and a first diffusion barrier layer formed between the aluminum member and the copper member. The copper member contains a plurality of bundles each having a multiplicity of fine filaments of Nb.sub.3 Sn embedded in a copper alloy and a second diffusion barrier layer surrounding the copper alloy. Preferably, the ratio m in the cross-sectional areas between the first diffusion barrier layer and the aluminum member is selected to meet the condition of 0.03.ltoreq.m<3. The aluminum member is disposed at the central portion of the superconducting wire.
