Superconducting wire material having laminated structure and manufacturing method therefor

A superconducting wire material comprising:

• a deposition substrate having a first width;
• a laminated structure comprising a buffer layer, a superconducting layer and a stabilization layer sequentially disposed on the deposition substrate, the buffer layer being disposed directly on the deposition substrate, the laminated structure having a second width which is smaller than the first width and recessed spaces at both ends in a width direction;
• a lamination substrate having a third width that is substantially the same as the first width of the deposition substrate;
• and
• a solder filling the recessed spaces thereby soldering the deposition substrate with the lamination substrate,
• wherein the stabilization layer includes first and second layers, the first layer including any one of gold, silver, platinum, palladium, and a combination thereof, the second layer including any one of copper, aluminum, and a combination thereof.
