PROBLEM TO BE SOLVED: To provide a winding device capable of suppressing the quality deterioration of a wound element.SOLUTION: At the tip part of an electrode sheet insertion mechanism 19 for supplying a negative electrode sheet 5 to a core 21, there are provided a pair of chucks 19A which can grasp the negative electrode sheet 5, and a guide mechanism 19B which can support a predetermined section of the negative electrode sheet 5 on the winding start end side than a part grasped by the chucks 19A. The guide mechanism 19B includes: a movable part 31 which includes a support roller 34, capable of supporting the electrode sheets 4, 5, and is movable along the supply direction of the negative electrode sheet 5; and a belt 36 which is pulled out from the movable part 31 side to the support section L side, accompanying the movement of the movable part 31 to the tip side in the sheet supply direction, and which is returned to the movable part 31 side from the support section L side to the movable part 31, accompanying the movement of the movable part 31 to the rear end side in the sheet supply direction. Thus, the support section L of the electrode sheets 4, 5 is configured to be capable of telescopic motion. |
