Abstract
A superconductor wire comprising a plurality of Nb--Ti superconductor filaments embedded in a copper matrix made of a copper alloy other than a two element copper alloy selected from the group consisting of a Cu--Ni alloy, a Cu--Sn alloy and a Cu--Mn alloy, wherein the resistivity (Z) at room temperature of the copper matrix is 2.times.10.sup.-8 .OMEGA.m to 65.times.10.sup.-8 .OMEGA.m, and the distance between superconductor filaments is not less than 0.0625.times.1/.sqroot.Z nm. The superconductor wire has a high critical current density, a small AC loss and improved workability.
