Superconductor and method of manufacturing same

A method of manufacturing a superconductor, the method comprising:

• preparing a substrate having a tape shape that extends in a first direction and having surfaces which are defined as a top surface, a bottom surface, and opposing side surfaces;
• forming a superconducting layer on the top surface of the substrate;
• forming a first stabilizing layer on the superconducting layer, the first stabilizing layer containing a first metal;
• and
• forming a protective layer on the first stabilizing layer, the protective layer containing a second metal that is different from the first metal, wherein,
• the forming the protective layer includes:
• melting the first metal;
• and
• coating the first stabilizing layer with the molten first metal to form a first alloy layer, which contains the first and second metals, between the first stabilizing layer and the protective layer, and
• the protective layer is formed to be in contact with opposing side surfaces of each of the substrate, the superconducting layer, and the first stabilizing layer, and the bottom surface of the substrate, the protective layer surrounding the substrate, the superconducting layer, the first stabilizing layer and the first alloy layer;
• forming a low melting point metal layer on the protective layer, the low melting point metal layer surrounding the protective layer and containing a third metal;
• forming a second alloy layer that is disposed between the protective layer and the low melting point metal layer, the second alloy layer surrounding the protective layer and being surrounded by the low melting point metal layer, the second alloy layer containing the second metal and the third metal.
