Abstract
A secondary battery includes a battery casing accommodating an electricity-generating element group, and a battery cover having through-holes and sealing an opening in the battery casing. A first face at one end of each of positive and negative electrode connecting plates, which are each formed from a single plate of metal, is connected to a non-coated section of the electricity-generating element group. A second face at the other end of each of the positive and negative electrode connecting plates is a face onto which a busbar is welded, and the second face is exposed outward from one of the through-holes. Insulating base materials are interposed between THE positive and negative electrode connecting plates and an outer circumference of each through-hole, the insulating base materials and the battery cover are connected by brazing, and the insulating base materials and the positive and negative electrode connecting plates are connected by brazing.
