PROBLEM TO BE SOLVED: To provide a laminated type secondary battery formed by containing and sealing an electrode tab in a case, excellent in liquid leakage resistance and high in reliability and energy density. SOLUTION: The case is favorably sealed and the mechanical reliability of a connected part is ensured by connecting an external electrode lead 150 by a bolt 170 and a nut 175 in a state that the electrode tab 120 is contained in the pouch case 140, thereby obtaining a laminated secondary battery with high energy density.
