Summary:A wire winding device (10) uses a large-sized supply bobbin (14), which has a large capacity and a large diameter, to highly precisely suppress a variation in tension which variation occurs when a coil (18) is formed by winding a wire material (12) at high speed with the wire material aligned with a winding frame (30). Rotation (the number of rotation, and timing) of the supply bobbin (14) relative to rotation of the coil (18) is controlled based on the difference between the amount of take-up of the wire material (12) taken up on the winding frame (30) side and the amount of pay-out of the wire material (12) paid out from the supply bobbin (14), and the control is performed such that the amount of the take-up and the amount of the pay-out agree with each other every moment. This can highly precisely suppress a variation in tension even if there are large differences between inertia of and the diameters of the coil (18) and the supply bobbin (14).
