PROBLEM TO BE SOLVED: To provide a winding method and a winding device for a band body capable of increasing quality and yield. SOLUTION: This winding method for a toroidal core 18 formed by winding a magnetic band sheet 15 comprises the steps of forming a core 17 in a cylindrical shape having a locking recess 17b opening to the outer peripheral surface thereof, inserting a locking bar 16 into the locking recess 17b to lock the tip part of the magnetic band sheet 15, rotating the core 17 and the locking bar 16 in synchronism with each other to wind the magnetic band sheet 15 on the core 17, and after moving the locking bar 16 to the core 17 to relieve the tip part of the magnetic band sheet 15, extracting the locking bar 16 and the core 17 from the toroidal core 18.
