Abstract
A composite barrier-type NbAl superconducting multifilament wire material comprises Nb barrier filaments, Ta barrier filaments, Nb bulk dummy filaments, and a Nb or Ta covering. In the composite barrier-type NbAl superconducting multifilament wire material, the Nb barrier filaments and Ta barrier filaments are disposed in the wire material so that the Nb barrier filaments are concentrated in a filament region near a core formed from the Nb bulk dummy filaments and only the Ta barrier filaments are disposed or the Nb barrier filaments are dispersed in the Ta barrier filaments in an outer layer portion formed from a region outside the Nb barrier filaments, excluding the Nb or Ta covering.
