Abstract
A manufacturing method for a superconducting wire which is a fine line made of an oxide superconductor, including the steps of forming the fine line by drawing a metal pipe filled with materials for the oxide superconductor, causing the materials to react to produce the oxide superconductor, heating the metal pipe at a temperature which is higher than the melting point of the metal material constituting the metal pipe.

A manufacturing method for a superconducting wire which has a fine line of an oxide superconductor comprising:
- a process for forming a fine line by drawing a metal pipe filled with an oxide superconductor;
- a process for heating said fine line at a temperature which is higher than the melting point of a metal material constituting said metal pipe so that a melt of said metal material fills gaps among crystal grains of said oxide superconductor;
- and
- a process for solidifying the melt of said metal material that fills the gaps.
