PROBLEM TO BE SOLVED: To provide a power storage device in which the worsening of sealability of a liquid inlet by a seal member can be suppressed.SOLUTION: A secondary battery 10 comprises: a lid 14; a liquid inlet 20; and ribs 21 provided on the lid. The ribs includes: a first rib 21a closer to a first long edge 14a of the lid 14 than the liquid inlet 20 in a first direction Y1; and a second rib 21b closer to a second long edge 14b. The first rib 21a and the second rib 21b are arrayed in the first direction Y1, and the liquid inlet 20 is sandwiched by them. In plan view of the lid 14, the length of the second rib 21b in its longitudinal direction is longer than that of the first rib 21a in its longitudinal direction.SELECTED DRAWING: Figure 2 |
