<p>PROBLEM TO BE SOLVED: To provide a power storage device including multiple power storage elements, in which deformation due to expansion of each power storage element can be suppressed effectively.SOLUTION: In a power storage device 1 including multiple power storage elements 10, each of the multiple power storage elements 10 includes a container 100, and a positive electrode terminal 200 and a negative electrode terminal 300 projecting from the container 100 in the same direction. The power storage device 1 includes a bus bar 150 for electrically connecting a first terminal, that is one of the positive electrode terminal 200 or negative electrode terminal 300 of a first power storage element 10a, and a second terminal of a second power storage element 10b that is the reverse polarity of the first terminal. The first power storage element 10a and second power storage element 10b are arranged side by side in a second direction crossing a first direction, in a state where the projecting directions of the first and second terminals are in the first direction and reversed from each other.</p> |
