PROBLEM TO BE SOLVED: To enhance productivity of a power source module.SOLUTION: A power source module includes: a plurality of electric storage elements 320a stacked in a stacking direction; end plates 321a sandwiching the plurality of electric storage elements 320a therebetween; and a plurality of stacking bars connecting the end plates 321a to each other. Each of the electric storage elements 320a includes: a terminal surface on which an electrode terminal is mounted; a bottom surface; and first and second side surfaces. Each of the stacking bars includes an extending portion extending parallel to the stacking direction and fastening portions extending parallel to the end plates. As viewed in the stacking direction, a total area of the fastening portions positioned in a region close to the terminal surface with respect to a center line between the terminal surface and the bottom surface of each electric storage element 320a is set larger than a total area of the fastening portions positioned in a region close to the bottom surface.SELECTED DRAWING: Figure 6 |
