| 1. An oxide superconducting wire comprising:
a first oxide superconducting wire having a first end portion;
a second oxide superconducting wire having a second end portion; and
said first oxide wire comprising at least a first superconducting filament surrounded by and in direct contact with a first
sheath at least at said first end portion;
said second oxide wire comprising at least a second superconducting filament surrounded by and in direct contact with a second
sheath at least at said second end portion;
said first oxide superconducting wire including a first outer surface defined by an outer surface of said first sheath and
a first edge surface defined by an end of said first superconducting filament and an end of said first sheath;
said second oxide superconducting wire including a second outer surface defined by an outer surface of said second sheath
and a second edge surface defined by an end of said second superconducting filament and an end of said second sheath;
said first outer surface forming a junction with said second outer surface by connecting said first outer surface to said
second outer surface, in a region of said first and second end portions, by a brazing filler metal disposed therebetween;
and
said first and second oxide superconducting wires having constant thicknesses along the length directions thereof; and
said first and second oxide superconducting wires tape-like and are so cut that said first and second end portions have end
surfaces inclined in the width directions across the widths of the tape-like wires.
