Abstract
A superconducting wire includes a main body portion, a substrate, and a cover portion. The main body portion includes a first main surface and a second main surface located opposite to the first main surface, and includes a superconducting material portion. The substrate supports the second main surface of the main body portion. The cover portion is formed at least on the first main surface of the main body portion. In the cover portion, surface roughness in a central portion in a width direction of the superconducting wire is smaller than surface roughness at an end portion in the width direction.
