Abstract
The bipolar secondary battery includes a power generation element including unit power generation elements stacked together and including bipolar electrodes stacked via separators, and current collecting plates arranged at both ends of the power generation element in the stacked direction of the unit power generation elements so as to be in contact with the power generation element, wherein the current collecting plates each include an electrically conductive layer and a resin film, the electrically conductive layer being formed on the resin film having a thermal shrinkage percentage of 2% or greater at a temperature of 150° C., and the separators have a higher thermal shrinkage start temperature than the resin films.
