Abstract
A secondary battery includes a stacked electrode assembly in which a plurality of positive electrode sheets and a plurality of negative electrode sheets are stacked. Current collector terminals include current collector plate portions each extending along a plane orthogonal to exposed portions of the positive electrode sheets and exposed portions of the negative electrode sheets. Each of base plate portions is continuous with the current collector plate portion and extends along one side of the electrode assembly that is orthogonal to one side thereof from which the exposed portions protrude. Each of the current collector plate portions includes a plurality of slits extending from a tip end of the current collector plate portion along a direction orthogonal to the base plate portion, and extending into a curved portion. The exposed portions are inserted in the slits of the current collector terminals.
