Provided is an electric storage device that can ensure sealing of a case that houses an electrode assembly. An electric storage device according to the present invention includes: an electrode assembly; a case that houses the electrode assembly, the case including a defining wall; a rivet that passes through the defining wall, the rivet having a body and an insertion part formed continuously with the body; a conductive member that is electrically connected to the rivet; and a sealing member arranged at least one of between the defining wall and the conductive member and between the defining wall and the body, wherein the insertion part has a portion that is inserted through the defining wall, the sealing member and the conductive member; the insertion part has a diameter smaller than that of the body at least in the portion inserted through the defining wall, the sealing member and the conductive member; the insertion part has a hollow shaft-shaped end with a non-through hole extending in an axial direction of the insertion part, the end being crimped in a state where the insertion part has been inserted through the defining wall, the sealing member and the conductive member; and a bottom of the non-through hole is located between the defining wall and the conductive member. |
