ABSTRACT:
Disclosed herein is a method of and an apparatus for fabricating an oxide superconducting wire which comprises a tape-type long base material and an oxide superconducting film formed thereon. The oxide superconducting film is formed by laser ablation of applying a laser beam (2) onto a target (4) while translating a long base material (6) along its longitudinal direction and depositing atoms and/or molecules scattered from the target (4) on the base material (6).
