ABSTRACT:
By rapidly heating a precursor wire having a multifilamentary structure in which multiple composite cores in which a composite compound of an Nb—Ga compound and Nb is embedded in Nb are embedded in Nb, Ta, Nb-base alloy or Ta-base alloy as a matrix material to a temperature range of 1400 to 2100° C. in 2 seconds, quenching the precursor wire at a rate of 5000° C./second or larger, and subjecting the precursor wire to additional heat treatment at a temperature range of 600 to 850° C. for 1 to 400 hours, a superconducting wire having a multifilamentary structure in which multiple composite cores in which a composite compound containing Nb3Ga of a stoichiometric composition embedded in Nb are embedded in Nb, Ta, Nb-base alloy or Ta-base alloy as a matrix material is obtained.
