Abstract: A process for manufacturing a superconducting elongated article such as a superconducting wire which is applicable for manufacturing a superconducting coil or the like. The process includes steps comprising filling a metal pipe with material powder of ceramic consisting of compound oxide having superconductivity, performing plastic deformation of the metal pipe filled with the ceramic metal powder to reduce the cross section of the metal pipe, and then subjecting the deformed metal pipe to heat-treatment to sinter the ceramic material powder filled in the metal pipe. The ceramic material powder may contain compound oxide having Perovskite-type crystal structure exhibiting superconductivity. The metal pipe may selected from a group comprising metals of Ag, Au, Pt, Pd, Rh, Ir, Ru, Os, Cu, Al, Fe, Ni, Cr, Ti, Mo, W and Ta and alloys including these metals as the base. The heat-treatment may be carried out at a temperature ranging from 700 to 1,000 .degree.C, The plastic deformation of the metal pipe filled with the ceramic metal powder may be performed in such manner that the cross section of the metal pipe is reduced at a dimensional reduction ratio ranging from 16 % to 92 % by wire-drawing or forging by means of dies, roller dies, or extruder.
