<p>PROBLEM TO BE SOLVED: To provide a power supply module and a power storage element capable of suppressing looseness of the power storage element and fixing the power storage element without considering an individual difference of the power storage element.SOLUTION: A power supply module comprises: a spacer 4 including an engagement convex part 40; and a battery 3 including an outer package 30, and an engagement recessed part 35 provided on an outer surface 33 of the outer package and abutting on the engagement convex part of the spacer 4. When the engagement convex part is press-fitted into the engagement recessed part from above, the engagement convex part is engaged with the engagement recessed part in a plastic deformation state. As a result, the engagement convex part of the spacer after press-fitting is tightly adhered to the engagement recessed part by its self-restoring force.</p> |
