Abstract: A system and a method for manufacturing a superconductor wire which can improve structure degree of texture with biaxial-alignment property, and a system and a method for manufacturing a superconductor wire having excellent crystal arrangement characteristics at low cost are provided. A method for manufacturing a metal wire comprises: a step of manufacturing a billet; a step of manufacturing a metal tape from the billet using a rolling process; and a step(S4) of recrystallizing the metal tape in a reductive atmosphere, wherein the metal tape recrystallizing step comprises a step of applying a predetermined magnetic field to the metal tape. The metal tape recrystallizing step comprises the step of performing one cycle of heat treatment process multiple times, wherein the one cycle of heat treatment process comprises: a step(S41) of applying a predetermined magnetic field to the metal tape at the Curie temperature or less; a step(S42) of applying a predetermined magnetic field to the metal tape while heating the metal tape to the Curie temperature or more; and a step(S43) of applying a predetermined magnetic field to the metal tape while rapidly cooling the metal tape to the Curie temperature or less.
