摘要： The present invention provides an oxide superconducting wire including a component provided in the form of a tape and a metal tape. The component in the form of a tape has an oxide superconducting member and a metal coating member formed mainly of silver and coating a surface of the oxide superconducting member. The metal tape, bonded in a heat treatment (e.g., fusion- or diffusion-bonded) to a surface of the component in the form of a tape, does not contain any superconducting material and it is formed mainly of silver and it also contains at least one component other than silver.

摘要： Powder including at least a superconducting phase is degassed (step S1). After the powder is filled in a silver pipe (step S2), the silver pipe is degassed at a high temperature (step S3). After a plurality of single-core wires are inserted into another silver pipe to attain a multi-core structure, the silver pipe is degassed at a high temperature (step S5). The silver pipe is sealed under a reduced pressure (step S6). Therefore, even when a multi-core superconducting wire is manufactured, a manufacturing method of a superconducting wire capable of preventing swelling of the wire caused by a residual gaseous component can be obtained.
