Provided is a secondary cell provided with an electroconductive member that is connected to a positive electrode terminal or a negative electrode terminal and has an area connected to a bus bar, wherein the secondary cell has a simple structure, and is provided with an electroconductive member that can be welded with high reliability to the positive electrode terminal or the negative electrode terminal, and to the bus bar. The secondary cell is provided with: an electrode body (10) having a positive electrode plate and a negative electrode plate; an outer package body (20) having an opening and containing the electrode body; a sealing body (21) for sealing the opening; terminals (15), (16) provided to the sealing body and connected to the positive electrode plate or the negative electrodeplate; and electroconductive members (17), (18) disposed on the outer side of the sealing body and connected to the terminals. The electroconductive member (18) has an overlap part in which one end ofan electroconductive plate-shaped member is folded back and the facing surfaces are overlapped, and a base part in which the surfaces are not overlapped, and the terminals are connected to the electroconductive member on the base part.
