Abstract | PROBLEM TO BE SOLVED: To produce an Nb3(Al, Ge) or an Nb3(Al, Si) compound system superconducting multiconductors that show high critical current density under a high magnetic field, without carrying out spheroidizing processing. SOLUTION: A single line is produced, in which at least Ge or Si is included 2at% or higher, and in which matrix metal is coated at the circumference of a complex body of an aluminum group rapidly solidified powder or an aluminum group rapidly solidified powder solidification forming body which has crystallization matter with the average thickness of 1 μm or less, and an Nb or an Nb alloy. Several tens to millions of these are bundled together, and then, a multi-wiring material coated with matrix metal is produced again, and it is heat processed at a prescribed temperature. Then, after subjected to cooling processing, by contacting a metal material for cooling, an Nb3(Al, Ge) or an Nb3(Al, Si) compound phase filament is formed, after being heat treated again at a prescribed temperature.
