Abstract
Disclosed is a method of joining Y-based oxide superconductors on joining two or more Y-based oxide superconductors made by melting process under pressure, characterized by incorporating REBa.sub.2 Cu.sub.3 O.sub.7-.delta. (RE=Y, Ho, Er, Tm or Yb), Ag and BaCuO.sub.2 -CuO type composition to the joining interface as an adhesive phase for joining. It becomes possible to easily make a joined material that does not deteriorate the superconductive characteristic at joined interface.
