Abstract
A secondary battery according to the invention includes six power generation elements and a case having six mounting spaces in which the power generation elements are disposed, respectively. A positive electrode connecting portion of a positive electrode current collector plate of one of the power generation elements adjacent to each other is connected via a connecting hole in a partition wall to a negative electrode connecting portion of a negative electrode current collector plate of the other power generation element, whereby the secondary battery is provided. The positive electrode connecting portion of the positive electrode current collector is formed so as to bend more easily in an approaching direction B, which is opposite to a detaching direction B, than a first positive electrode plate welded portion and a positive electrode plate adjacent distal portion, where bending portions are provided on both sides, do.
