ELECTRICITY STORAGE DEVICE AND METHOD FOR MANUFACTURING ELECTRICITY STORAGE DEVICE

摘要

According to the present invention, a tab group (36) has: a first bent portion (36a) that is at a first end of the lamination direction L of an electrode assembly (12) in a laminated state and is bent toward a second end of the lamination direction L of the electrode assembly (12); and an extending portion (36b) that protrudes from the first bent portion (36a) in the lamination direction L. The tab group (36) is electrically connected to a conductive member (51) by means of a conduction part (W) that is positioned in the extending portion (36b). The conductive member (51) comprises: a fixation piece (52) that is affixed to the inner surface of a cover member (15) and intervenes between the extending portion (36b) and the cover member (15); and a connection piece (53) that intersects with the fixation piece (52) and protrudes toward the electrode assembly (12). The tab group (36) is electrically connected to the connection piece (53) by means of the conduction part (W) that is positioned in the extending portion (36b).
