ABSTRACT:
A non-superconductive Ag-based sheath formed surrounding a superconducting tape or wire is stripped by placing a Bi- or Pb-based metal material on the Ag-based sheath to be removed; and then heating the Bi- or pb-based metal material to 250.degree. C.-450.degree. C. to dissolve the Ag-based sheath; and removing the dissolved Ag-based sheath.
