Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a power storage element of high quality in which a caulked part between conductive members is less likely to loosen even if force or vibration is applied.SOLUTION: A power storage element comprises: an electrode body, a case, an external terminal, a terminal connection bar 13, a power collector 21, and a rivet 18. The case comprises a sealing body 101. The rivet 18 passes through the sealing body 101, power collector 21, and terminal connection bar 13, thereby electrically connecting the power collector 21 and the terminal connection bar 13. The leading end of the rivet 18 is caulked. A female thread is formed on the internal wall of the hollow part of the rivet 18, and a screw 26 is inserted. The head 26b of the screw 26 is in contact with the caulked part 18b.SELECTED DRAWING: Figure 4 【課題】力や振動が加わったりした場合にも、導電部材間のカシメ部が緩み難く、高い品質を有する蓄電素子を提供する。【解決手段】蓄電素子は、電極体、ケース、外部端子、端子接続バー１３、集電体２１、リベット１８を備える。ケースは、封口体１０１を備える。リベット１８は、封口体１０１、集電体２１、端子接続バー１３を貫通し、集電体２１と端子接続バー１３とを電気的に接続する。リベット１８の先端はカシメられている。リベット１８の中空部の内壁に雌ネジが形成され、ネジ２６が挿入されている。ネジ２６の頭部２６ｂは、カシメ部１８ｂに接している。【選択図】図４
