PURPOSE: An electrical storage device is provided to prevent formation of gaps between a case and a conductive member while conducting a current collector, the case, and the conductive member. CONSTITUTION: An electrical storage device comprises a case in which mounting holes(3B) are formed, an electrode assembly(2) having positive electrode and cathode and is accepted within the case, a current collector(13) in which one end is connected to anode or cathode of the electrode material, and the other end is electrically connected to the case, an inner packing portion(14) which is in contact with a part between the mounting holes and the other end of the current collector, and a conductive element in which the other end of the current collector and the inner packing part are inserted into.
