Original Abstract Submitted

A power storage device includes a case having a metal lid with an insertion hole, a terminal member inserted through the insertion hole, and a resin member insulating between the case and the terminal member. The lid has a surface facing outside, including a ring-shaped hole-surrounding region around the insertion hole, to which the resin member is airtightly firmly fixed, and an outer region contacting the resin member. A two-region consisting of two, the hole-surrounding region and the outer region, has a two-region length at a two-region length ratio of 3.0 or more, which is the ratio of the maximum two-region length to the minimum two-region length, and a seal length of 1.4 or less, which is the ratio of the maximum seal length to the minimum seal length of the hole-surrounding region.
