To provide a spacer which is to be disposed between a first power storage cell and a second power storage cell arranged in a first direction and in which a reduction in cooling efficiency for cooling each power storage cell is suppressed.SOLUTION: A spacer includes: a main body portion 30B which faces a main surface and in which a cooling passage 49B is formed through which cooling air flows between the main surface and the cooling passage; a side wall portion 32B which is connected to one end of the main body portion 30B in a second direction, provided on a first lateral surface side, and in which a communication portion communicating with the cooling passage 49B is formed; an end plate portion 36B which is connected to one end of the side wall portion 32B in a third direction, provided on a first end face side, and formed to extend from one end of the side wall portion 32B in the second direction; and a lip portion 50B which is formed on the end plate portion 36B and protruding toward the first end face side. A gap is formed between the side wall portion 32B and the first lateral surface and between the end plate portion 36B and the first end face, and the lip portion 50B contacts the first end face.SELECTED DRAWING: Figure 3 【課題】第１方向に配列する第１蓄電セルおよび第２蓄電セルの間に配置されるスペーサであって、各蓄電セルを冷却する冷却効率の低下が抑制されたスペーサを提供する。【解決手段】スペーサは、主面と向かい合うと共に、主面との間に冷却風が流れる冷却通路４９Ｂが形成された本体部３０Ｂと、第２方向において本体部３０Ｂの一端に接続されると共に第１側面側に設けられ、冷却通路４９Ｂに連通する連通部が形成された側壁部３２Ｂと、第３方向において側壁部３２Ｂの一端に接続されると共に第１端面側に設けられ、側壁部３２Ｂの一端から第２方向に延びるように形成された端板部３６Ｂと、端板部３６Ｂに形成されており、第１端面側に向けて突出するリップ部５０Ｂとを含み、側壁部３２Ｂおよび第１側面の間と、端板部３６Ｂおよび第１端面との間には、隙間が形成されており、リップ部５０Ｂは第１端面と接触する。【選択図】図３
