PURPOSE:To make it possible to obtain a superfine oxide superconductive fiber easily by using a solution including a high polymer compound in which an oxide superconductor or a substance to be an oxide superconductor by heat- treatment is scattered or solved as a spinning material solution, spinning in a dry type spinning to obtain a precursor fiber of a superconductive fiber, and then applying a heat treatment. CONSTITUTION:An oxide superconductor or a substance to be an oxide superconductor by heat-treating is scattered or solved in a solution including a high polymer compound to produce a spinning material solution, which is dry-spun into a precursor fiber of a superconductive fiber, and after that, a heat treatment is applied. The oxide superconductor or the substance to be an oxide superconductor by heat-treating to be used is preferably used as a powder, especially a powder less than 15mum, preferably less than 1mum, and more preferably as a micropowder less than 0.5mum. In such a way, a superfine wire material of an oxide superconductor can be obtained. |
