Abstract
A prismatic secondary battery in which a deformation plate becoming deformed when a pressure inside the battery becomes equivalent to or higher than a predetermined value is disposed in a conductive path between a positive electrode plate and a positive electrode terminal. A positive electrode collector electrically connected to the positive electrode plate includes a collector body portion disposed on an electrode body side of the deformation plate, a collector connection that extends from an end of the collector body portion in a longitudinal direction of a sealing plate towards the sealing plate, and a lead portion that extends from the collector connection in the longitudinal direction of the sealing plate. A positive electrode tab portion is connected to the lead portion.
