1. A method of manufacturing a flexible, high temperature superconductive cable, comprising the steps of:

  • longitudinally imbedding a ceramic oxide material having high temperature, superconductive characteristics in a band source member of metallic material thereby encasing longitudinal surfaces of said ceramic oxide material in said metallic material;

    compressing by a rolling process said band source member and said encased ceramic oxide material into an elongated flat band with the length of said encased ceramic oxide material being extended to the length of said elongated flat band and forming a high temperature superconductor therethrough;

    deforming by longitudinal drawing and shaping said elongated flat band into a hollow tubular member;

    welding longitudinal adjacent edges of said hollow tubular member; and

    corrugating said welded, hollow tubular member.
