ABSTRACT OF THE DISCLOSURE A method of manufacturing a superconducting wire is carried out by first preparing a material being composed of Y1Ba2Cu3O7. This material is heated/molten in a platinum crucible. A melt thus obtained is drawn out from a hole provided on the bottom wall of the crucible to be linearly discharged. The linearly discharged melt is cooled to be solidified. A cooling/solidifying space for such a step is set at a temperature level lower by about 10°C than the solidifying point of the material, and a slow-cooling zone is provided next to the cooling/solidifying space. This slow-cooling zone is provided to be at a relatively high temperature in a portion closer to the hole while having a temperature gradient along a direction for linearly discharging the melt. A superconducting wire being composed of Y1Ba2Cu3O7 is thus obtained. This superconducting wire superconducts at 85 K.
