Abstract

A method of manufacturing a secondary battery including an electrode body element fabricating step in which a first electrode body element including a positive electrode plate and a negative electrode plate, and a second electrode body element including a positive electrode plate and a negative electrode plate are fabricated, a tab-connecting step in which a first positive electrode tab group of the first electrode body element and a second positive electrode tab group of the second electrode body element are connected to a second positive electrode collector, and a first negative electrode tab group of the first electrode body element and a second negative electrode tab group of the second electrode body element are connected to a second negative electrode collector, and an electrode body fabricating step in which, after the tab-connecting step, the first electrode body element and the second electrode body element are unified.
