To reduce the stress in an electrode by eliminating the dimensional difference due to tolerance and thermal expansion of each storage element in a power storage module and facilitating assembling.SOLUTION: Disclosed is a power storage module BM100, BM which includes: a plurality of power storage elements 10; a connection conductor 20 which connects the power storage element 10; a metal-made case 50 for housing a power storage unit BU therein; and holding members 40, 140 for holding the power storage elements. The holding members 40, 140 include a cap 41 into which the power storage element 10 is fitted; a fixing part 42 fixed to the case 50; and a resin elastic part 43 which is provided between the cap 41 and the fixing part 42 in an expanding and contracting manner and made of a resin.SELECTED DRAWING: Figure 1 【課題】蓄電モジュールにおいて各蓄電素子の公差および熱膨張による寸法差を解消し、組み付けを容易にするとともに電極におけるストレスを軽減する。【解決手段】複数の蓄電素子１０と、蓄電素子１０を接続する接続導体２０と、蓄電ユニットＢＵを収容するための金属製のケース５０と、前記蓄電素子を保持する保持部材４０，１４０と、を備える蓄電モジュールＢＭ１００，ＢＭであって、保持部材４０，１４０は、蓄電素子１０が嵌め入れられるキャップ４１と、ケース５０に固定される固定部４２と、キャップ４１と固定部４２との間に伸縮可能に設けられ、樹脂で構成される樹脂弾性部４３と、を備える。【選択図】図１
