<p>A method of producing a superconducting wire comprises the steps of (a) preparing a superconducting precursor powder by treating a material powder for a superconducting use, (b) packing a first metal pipe with the superconducting precursor powder, and (c) sealing the first metal pipe. In the method, the step of packing the first metal pipe and the step of sealing the first metal pipe are performed in an atmosphere under a reduced pressure to reliably perform a degassing treatment of the superconducting powder. Thus, a method of producing a superconducting wire excellent in superconducting property, particularly a critical current, is offered. A production method of a superconducting multifilament wire is offered. A superconducting apparatus produced through these methods is offered.</p> |
