Abstract
A laminated battery includes an electrode body and a laminate film that covers and seals the electrode body inside. The laminate film has a fused portion formed by superposing end portions of the laminate film and fusing together their inner surfaces. The fused portion has three or more bend portions including two or more fold portions that are bent in angular or arcuate shapes so as to have an angle of 90° or less and one distal end-side bend portion that is bent in an angular or arcuate shape so as to have an angle less than 180° in a position closest to a distal end of the fused portion. The fused portion has a shape in which at least part of the distal end faces the electrode body side.
