PROBLEM TO BE SOLVED: To provide a power storage device capable of maintaining a relative position between a termination member and a coupling member at a proper position even if the termination member and the coupling member are fastened by a screw member.SOLUTION: A power storage device includes a power storage element, a termination member, a coupling member and a screw member. The coupling member has a connection part overlapped on the termination member, and a beam part extending from the connection part. The connection part has a first abutting part provided at a position separated from an insertion position of a shaft part of the screw member. The termination member has a second abutting part with which the first abutting part abuts from the rotation direction of the screw member. 【課題】終端部材と連結部材とをネジ部材によって締結しても、終端部材と連結部材との相対位置を適正な位置に維持させることのできる蓄電装置を提供する。【解決手段】本発明に係る蓄電装置は、蓄電素子と終端部材と連結部材とネジ部材とを備え、連結部材は、終端部材に重ね合わされる接続部と、該接続部から延出する梁部とを有し、接続部は、ネジ部材の軸部の挿通位置から離間した位置に設けられた第一の当接部を有し、終端部材は、ネジ部材の回転方向から第一の当接部が当接する第二の当接部を有する。【選択図】図４
