    摘要： A power storage device includes: a plurality of power storage modules; a conductive member; a pair of restraint members; and an adhesive member. Each power storage module includes: an overlapping region that overlaps with the pair of restraint members in a stacking direction; and a non-overlapping region that does not overlap with the pair of restraint members in the stacking direction. Each power storage module includes: a direct contact region that is in direct contact with the conductive member; and an indirect contact region that is in contact with the power storage module adjacent to that power storage module or the conductive member, with the adhesive member interposed therebetween. The overlapping region includes the direct contact region, and the non-overlapping region includes the indirect contact region.
