Summary:PROBLEM TO BE SOLVED: To provide a power storage module which allows for reduction in man-hour required for assembling a power storage module by stacking power storage cells.SOLUTION: A power storage module includes a plurality of unit cells stacked one another. Each of unit cells contains a plurality of power storage cells containing a pair of electrode tabs; a frame body housing power storage cells; and a support plate attached to the frame body and supporting a plurality of power storage cells at a first side. Openings are provided between an inner periphery of the frame body and an outer periphery of the support plate so as to correspond to each of electrode tabs. One electrode tab of at least one of power storage cells passes through the opening corresponding to the electrode tab and reaches a second side opposite to a first side of the support plate, and the other electrode tab does not pass through the opening corresponding to the electrode tab and is arranged at the first side of the support plate. An insertion inhibit part for inhibiting the electrode tab from passing through the opening, is provided so as to overlap with the electrode tab not passing through the opening in a plan view. 【課題】 蓄電セルを積み重ねて蓄電モジュールに組み立てる工数を削減することが可能な蓄電モジュールを提供する。【解決手段】 積み重ねられた複数のセルユニットにより、蓄電モジュールが構成される。セルユニットの各々は、一対の電極タブを含む複数の蓄電セルと、蓄電セルを収容する枠体と、枠体に取り付けられ、複数の蓄電セルを一方の第1の側に支持する支持板とを含む。電極タブの各々の位置に対応して、枠体の内周と支持板の外周との間に開口部が設けられている。少なくとも1つの蓄電セルの一方の電極タブは、当該電極タブに対応する開口部を通って、支持板の第1の側とは反対側の第2の側に達しており、他方の電極タブは、当該電極タブに対応する開口部を通ることなく、枠体の第1の側に配置されている。さらに、平面視において、開口部を通っていない電極タブと重なり、電極タブが開口部を通過することを阻害する挿入阻害部が設けられている。【選択図】 図5
