PURPOSE:To decrease the distortion arising from a rewinding in the manufacturing method of a winding core of a permalloy or the like with a big outside diameter by positioning a core, prior to winding, in the ring having an inside diameter corresponding to the outside diameter of the desired winding core and by rewinding the coil by rotating it along the inside circumference. CONSTITUTION:A before-rewinding core 3 is positioned in a ring 5 having an inside diameter corresponding to the outside diameter of the desired winding core, and the winding terminal end 4 of the before-rewinding core 3 is fixed to the inside of the ring 5. Then the core 3 is rotated along the inside circumference of the ring 5 and the rewinding is performed. |
