Abstract

To provide a battery pack (100) capable of, even if an electrode area is large, easily applying a proper pressing pressure to a laminated body (140) in which unit cells (10) are laminated one on another. The battery pack (100) has a laminated body (140) in which unit cells (10) are laminated one on another, a cell case (120) having a first opening (126) and containing the laminated body (140), and a first lid member (170) to tightly close the first opening (126). The first opening (126) is positioned to face, in connection with a unit cell laminated direction S, a first face (142) of the laminated body (140). The first lid member (170) is configured to, if an internal pressure of the cell case (120) is lower than atmospheric pressure, deform while keeping the tightly closing state, come into contact with the first face (142) of the laminated body (140), and apply a pressure based on a differential pressure between atmospheric pressure and the internal pressure of the cell case (120) to the contacting face.
