Abstract: A battery including an outer casing, positive and negative electrodes provided in the outer casing, and an electrolyte provided therebetween. The outer casing is electrically connected to one of the positive and negative electrodes to constitute one of electrode terminals. The other is connected to the other electrode terminal which is electrically insulated from the outer casing. At least one of the positive and negative electrodes and the electrode terminal are connected to each other through a collector, which includes a plate-shaped body section and a connecting piece extended in an almost vertical direction from an end of the body section. 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.
