Abstract
A precursor for manufacturing a Nb3Sn superconducting wire by bronze method, in which plural Nb or Nb-based alloy cores are buried in a Cu—Sn-based alloy base material. The Cu—Sn-based alloy base material comprises Ti and/or Zr in addition to Sn, and these components satisfy the equations (1) and (2) below: 0.4≦(X−15.6)/Y≦1.9 (1) and 15.6<X≦19 (2) where the symbol X denotes the content of Sn in mass % and the symbol Y denotes the total content of Ti and Zr in mass %.
