A superconducting wire includes a multilayer stack and a covering layer (stabilizing layer or protective layer). The multilayer stack includes a substrate having a main surface and a superconducting material layer formed on the main surface. The covering layer (stabilizing layer or protective layer) is disposed on at least the superconducting material layer. A front surface portion of the covering layer (stabilizing layer or protective layer) located on the superconducting material layer (front surface portion of the stabilizing layer or upper surface of the protective layer) has a concave shape.

Superconducting wire

An oxide superconducting wire includes an oriented metal substrate, an intermediate layer formed on the oriented metal substrate, and an oxide superconducting layer formed on the intermediate layer. The oriented metal substrate has an in-plane orientation &#x394;&#x3d5; of 7&#xb0; or less. The intermediate layer is formed of a single layer.

Oxide superconducting wire

A superconducting wire includes: a substrate having a first main surface and a second main surface opposite to the first main surface; and a superconducting material layer disposed on the first main surface of the substrate. The superconducting material layer is disposed to cover at least a part of a side surface of the substrate in a width direction of the substrate.
