1. A battery module, comprising:
- a plurality of stacked cells being stacked, in each of which an electrolyte solution and a power generation element formed by stacking electrode plates are hermetically sealed by a package formed by a sheet, and electrode terminals connected individually to the electrode plates of the power generation element are drawn outward from the package formed by a sheet;
a pair of pressuring members arranged in a stack direction where the stacked cells are stacked;
a pressing mechanism for applying a pressing force between the pair of pressuring members to pressure the stacked cells in the stack direction; and
a managing member which manages a state of pressing the stacked cells by the pressing mechanism.

Abstract
A plurality of cell units 10a made of stacked cells 10 are stacked. Pressing mechanisms 30 and 31, which apply a pressing force between a pair of pressuring members 20 arranged in a stack direction where the cell units 10a are stacked, are provided, and the cell units 10a are pressured in the stack direction. A state in which the cell units 10a are pressed by the pressing mechanisms 30 and 31 is managed by a managing member 32. Thus, a state where electrode plates of power generation elements 11 are pressed is maintained, and the pressed state of the power generation elements 11 can be precisely managed by the managing member 32.
