Original Abstract Submitted
A battery includes a layer-type electrode body, a laminate exterior body, a positive electrode tab, and a negative electrode tab. In the electrode body, a positive electrode sheet and a negative electrode sheet are alternately layered in a layering direction via a separator sheet. The positive electrode tab protrudes from the laminate exterior body toward one side in a first direction orthogonal to the layering direction. The negative electrode tab protrudes from the laminate exterior body toward the one or another side in the first direction. The electrode body has an overlap region in which only plural separator sheets overlap at both edge regions in a second direction orthogonal to the layering direction and to the first direction. At least one of the two overlap regions has plural welded portions at which the plural separator sheets are welded. The plural welded portions are discretely formed along the first direction.
