PURPOSE:To avoid the impairment and the characteristic deterioration of the superconductive wire by winding the hollow conductor round the winding barrel along the ultra-thin and multi-core conducting wire and then fixing such superconductive wire to the hollow conductor via the low fusing point metal. CONSTITUTION:Hollow conductor 3 is supplied continuously to winding barrel 5, and at the same time tape 6B composed of the low fusing point metal, ultra-thin and multi-core superconductive wire 4 and tape 6A of the low fusing point metal are led in that order and continuously along each of grooves 2a-2d of hollow barrel 3. Then insulator tape 7 is wound round barrel 3 to be taken up continuously through rotations of barrel 5. After this, the fusing is given in the vacuum or non- oxidizing atmosphere at the temperature under the fusing points of tape 6A and 6B, and then the fused substance thus obtained is permeated between each composition wire inside wire 4 and also supplied sufficiently into the groove inner surface of barrel 3 as well as to wire 4. After this, the low fusing point metal is cooled down and solidified, and thus wire 4 can be fixed firmly to the groove of conductor 3.
