Abstract
In a sealed battery, a metal current carrying blockA having a protrusionon each of the two opposing faces is placed between positive or negative electrode substrate exposed portions that are divided into two so as to bring the protrusionon each of the two opposing faces into contact with the positive or negative electrode substrate exposed portions that are stacked, a pair of electrodesandfor resistance welding are brought into contact with positive electrode collector membersor negative electrode collector members that are each placed on the outermost surfaces of the positive electrode substrate exposed portionsor negative electrode substrate exposed portions, and resistance welding is performed with pressure applied between the pair of electrodesandfor resistance welding.
