PURPOSE: To simplify a process and to reduce man-hours with few jigs, by pushing/burying a superconductive wire and winding it in an edge of a grooved part of a cylindrical bobbin which is grooved in a shape of a saddle-shaped coil and next by forming a saddle-shaped coil from an outer circular side.

CONSTITUTION: A cylindrical bobbin 4 is prepared to be grooved in a shape of a saddle-shaped coil. This bobbin is mounted on a turn table 5. While a flat-type superconductive wire 7 is pushed on an edge 6 of a grooved part of the bobbin, a turntable 5 is turned to rotate the cylindrical bobbin 4. The superconductive wire 7 is supplied from a drum 8. The saddle-shaped coil 1 is wound serially from an outer circular side to an inner circular side in this way. After winding of the coil around one pole is finished, the cylindrical bobbin 4 is turned upside down and the coil is wound around the other pole to obtain a saddleshaped superconductive magnet.
