<p><P>PROBLEM TO BE SOLVED: To provide a superconductive coil capable of appropriately holding an allowable current value in the superconductive coil by reducing the tensile stress of a superconductive layer caused by a difference in the thermal coefficient of expansion between the substrate of a superconductive tape wire and a reinforced tape wire. <P>SOLUTION: The superconductive tape wire 11 and the reinforced tape wire 21 are laminated and connected to a first electrode terminal 34 provided at a winding core 33 of a roll frame 31, the roll frame 31 is rotated, and the superconductive tape wire 11 is rewound from a bobbin 45 without applying any back tension and taken up on an outer-periphery surface of the winding core 33. While applying back tension, the reinforced tape wire 21 is rewound from a bobbin 47 and wound around the outer-periphery surface of the winding core 33 together with the superconductive tape wire 11. After completing winding both the superconductive tape wire 11 and reinforced tape wire 21, termination sections of the superconductive tape wire 11 and reinforced tape wire 21 are connected to a second electrode terminal 35. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
