Abstract
A power storage device includes an electrode assembly, a case, first and second electrode terminals, and a current interrupting mechanism. The current interrupting mechanism interrupts a current through an electrical current-carrying path when the internal pressure of the case reaches a preset pressure. The current interrupting mechanism includes a mechanism insulating portion, which insulates the first electrode terminal including the current interrupting mechanism from an end face of the electrode assembly, and a terminal insulating portion, which insulates the second electrode terminal from the end face of the electrode assembly. The projecting dimension from a wall portion to the mechanism insulating portion including the first electrode terminal is equal to the projecting dimension from the wall portion to the terminal insulating portion including the second electrode terminal.
