PROBLEM TO BE SOLVED: To making the weld bond easily with improving the bond work, by winding a terminal wire of a very-low-resistance conductor on a terminal board, winding an oxide superconductor wire and a reinforcing insulation wire round the terminal wire, winding a terminal wire of a very-low-resistance conductor around it, and heat treating them. SOLUTION: A groove is cut into the outside face of a tubular bobbin, a terminal board 4 made of a very-low-resistance conductor i.e., Au or Cu alloy is projected from the end face of the tubular bobbin in the lengthwise direction and inserted in the groove so as to be flush with the outside face, the entire outside face of the tubular bobbin is insulated with an oxide film 17, a thicker very-low-resistance conductor 7a than an oxide superconductor wire 8 wound around the outside face is wound, the oxide superconductor wire 8 and reinforcing wire 9 are bonded and wound round the side face of the terminal wire 7, the oxide superconductor wire 8 is wound and fixed with the terminal wire 7b of the very-low-resistance conductor and heat treated. |
