Power storage device

Abstract

A power storage device comprises: at least one battery cell equipped with a cell case; a discharge valve that is provided at a first bottom section, which is a bottom section of the battery cell, and that performs valve-opening when an internal pressure of the cell case has attained a specific value; a battery case that houses the battery cell; an uneven surface portion that is formed at at least one of the first bottom section or a second bottom section, which is a bottom section of the battery case, and that is disposed at a different position from the discharge valve when viewed in a vertical direction; and a deformable thermal conduction material that is adhered to the first bottom section and the second bottom section so as to contact the uneven surface portion while avoiding the discharge valve.
