Abstract
Provided is a battery module that allows suppressing impairment of battery performance, through suitable control of a restraining pressure that is exerted in the stacking direction of a stack, also in a case where unit cells expand/shrink when charged/discharged. The battery module is provided with a stack in which a plurality of unit cells is stacked, and with a pressure regulation member, which is disposed at least at one site from among a gap between the stacked unit cells, and a first end and a second end in the stacking direction, and which regulates a restraining pressure exerted in the stacking direction of the stack. The pressure regulation member is provided with a liquid holding section and a liquid storage section. The liquid holding section is provided with a liquid holding body capable of holding a liquid. The liquid storage section has a space capable of storing the liquid.
