Patent ID: 6979514

Claim:
A battery comprising: an outer casing that functions as a first electrode terminal by electrically connecting the outer casing to one of positive and negative electrodes; a second electrode terminal which is electrically insulated from the outer casing and connected to the other one of the positive and negative electrodes through an electrode tab, a collecting tab and a collector; and a laminated product provided in the outer casing in which the positive and negative electrodes and an electrolyte are laminated, wherein said electrode tab is connected to the other one of the positive and negative electrodes to be exposed from an upper end face of the laminated product, and said electrode tab and said collector are connected by said collecting tab such that the electrode tab is connected at one end portion of the collecting tab whereas the collector is connected to an opposite end portion thereof, wherein, the collector includes a plate-shaped body section and a connecting piece extended in a downward direction from an end of the body section, one of the body section or the connecting piece is provided with a bending guide section which can be bent in such a direction that the connecting piece approaches the body section, wherein said connecting piece of the collector and the collecting tab with said bending guide section being bent are disposed in a space between an upper end of the electrode tab and the upper end face of the laminated product.
