Method for manufacturing wound electrode body, method for manufacturing storage device including the wound electrode body, and wound electrode body manufacturing device for the same

A method for manufacturing a wound electrode body, the wound electrode body being configured such that a strip-shaped positive electrode sheet and a strip-shaped negative electrode sheet are stacked with a strip-shaped separator sheet interposed therebetween and an obtained stacked body is wound and that the separator sheet and the positive electrode sheet are bonded via an adhesion layer and/or the separator sheet and the negative electrode sheet are bonded via the adhesion layer, the method comprising:

• preparing the positive electrode sheet, the negative electrode sheet, and the at least one separator sheet;
• conveying each of the prepared sheets;
• and
• winding each of the conveyed sheets around a winding core,
• wherein
• in the preparing, at least one sheet of the positive electrode sheet, the negative electrode sheet, and the separator sheet includes the adhesion layer on at least one surface thereof and the surface including the adhesion layer includes a region where the adhesion layer is arranged and a region where the adhesion layer is not arranged, and
• in the conveying, the sheet including the adhesion layer is conveyed such that the region where the adhesion layer is not arranged contacts a roller.
