The invention relates to a spirally-wound electrode and a method of manufacturing the spirally-wound electrode. In the spirally-wound electrode, in a first region, short sides of first and second separator sheets on an inner side are aligned with each other. In a second region, a negative electrode sheet, the first separator sheet, a positive electrode sheet, and the second separator sheet are arranged from an inner side toward an outer side in a radial direction. The second region extends from a position where short sides of the negative and positive electrode sheets on the inner side are aligned with each other in a same phase to a short side of the positive electrode sheet on an outer side. In a third region, the negative electrode sheet, and the first and second separator sheets are arranged from the inner side toward the outer side in the radial direction. The third region extends to a short side of the negative electrode sheet on the outer side.
