PURPOSE:To make ceramic-based superconductive material into wire, tape, etc., by filling the ceramic-based superconductive material in an aluminum pipe and wire-drawing the pipe. CONSTITUTION:Constituents of a superconductive material (Ba.Y.Cu.O), (Ba.La.Cu.O), (Sr.La.Cu.O), (Ba.Sc.Cu.O) and (Ca.La.Cu.O) are filled into an aluminum pipe. Setting the wire-drawing temperature of the aluminum pipe below the melting point of aluminum, the aluminum pipe is wire-drawn. According to this constitution, it is possible to make the ceramic material easily into wire material, tape, coil, etc., without deteriorating the superconductivity of the ceramic material and to greatly contribute to the practical use of the ceramic material.
