Abstract
An electrode body including positive electrode plate and negative electrode plate includes a positive electrode tab portion at an end portion on the sealing plate side. The positive electrode plate is electrically connected to a positive electrode collector including a collector body portion and a collector connection. A pressure-sensitive current breaking mechanism includes a conductive member including an opening portion on an electrode body side, a deformation plate that seals the opening portion, and a collector body portion that is disposed on the electrode body side of the deformation plate and that is connected to the deformation plate. The collector connection is disposed between the current breaking mechanism and one of the large-area side walls of the prismatic outer package, and the positive electrode tab portion is connected to the collector connection.
