Title: Superconducting wire and method of manufacturing the same

Abstract: A starting material which is converted to a continuous body of an oxide superconductor by a heat treatment is filled in a tubular Ag sheath member. The diameter of the filled member is reduced by extrusion to form a wire. The wire is subjected to a heat treatment so that the starting material inside the sheath member is converted to a continuous body of an oxide superconductor. A superconducting wire constituted by the sheath member and the oxide superconductor filled inside the sheath member is obtained. A superconducting coil can be obtained by winding the superconducting wire.
