Abstract
The battery pack has a laminated body in which unit cells are laminated one on another, a cell case having a first opening and containing the laminated body, and a first lid member to tightly close the first opening. The first opening is positioned to face, in connection with a unit cell laminated direction, a first face of the laminated body. The first lid member is configured to, if an internal pressure of the cell case is lower than atmospheric pressure, deform while keeping the tightly closing state, come into contact with the first face of the laminated body, and apply a pressure based on a differential pressure between atmospheric pressure and the internal pressure of the cell case to the contacting face.
