POWER STORAGE DEVICE

A power storage device includes: an electrode assembly formed by stacking a plurality of electrodes; and a conductive member that is in contact with the electrode assembly. The conductive member includes: a conductive member body (411) that overlaps with the electrode assembly in a stacking direction; and a current collector terminal (412). The conductive member body (411) includes: an insulated region (R10) insulated from the electrode assembly; and an electrically conducting region (R20), at least a part of the electrically conducting region being electrically connected to the electrode assembly. A distance between the current collector terminal (412) and the electrically conducting region (R20) is greater than a distance between the current collector terminal (412) and the insulated region (R10).
