摘要： In a stacked secondary battery, positive electrodes 5 and negative electrodes 4, which are formed by integrally forming a positive electrode collector tab 57 and a negative electrode collector tab 47 on a metal foil positive electrode collector 51 and a metal foil negative electrode collector 41, respectively, are stacked together with separators 6 disposed in-between. The separator 6 is also disposed between the opposing parts 8 of the positive electrode collector tab and the negative electrode collector tab. A positive electrode lead 17 and a negative electrode lead 15, connected to the positive electrode collector tab and the negative electrode collector tab, respectively, extend out from the same end surface of the stack of the positive electrodes 5 and the negative electrodes 4 and are drawn out from an outer casing 3.
