PROBLEM TO BE SOLVED: To improve a high rate discharging characteristic of a storage battery and to mass produce efficiently. SOLUTION: This storage battery is provided with a power generating element formed by laminating a positive electrode plate and a negative electrode plate, an outer can containing the power generating element, a sealing body closing up the outer can and provided with one electrode terminal, and a current collector 6 electrically connecting the one electrode plate of the power generating element to the electrode terminal of the sealing body. The collector 6 is constituted by one metal plate. The collector 6 being a metal plate is composed of a collecting part 6A connected to the electrode plate, and a lead part 6B extended from the periphery of the collecting part 6A to be connected to the sealing body 5 serving also as the electrode terminal 7. An intermediate portion of the lead part 6B is overlapped with the collecting part 6A by folding a base part 6C. A part of the lead part 6B overlapped with the collector 6 is deposited to the collecting part 6A.
