Abstract
A secondary battery includes a power generation element including a plurality of electrodes. The electrodes are stacked on each other in a stacking direction with a separator interposed therebetween. Each of the electrodes includes a current collector led out in a first direction intersecting the stacking direction. Each of a plurality of current collectors led out in the first direction includes an end part, and the end part includes a first bent part that is bent in a second direction intersecting the first direction. Each of a plurality of first bent parts overlaps and is in contact with an adjacent first bent part in the second direction. At least one of the first bent parts terminates at a middle point on an end face along the second direction of the power generation element.
