Zusammenfassung:	An electric storage device 10 has an electrode laminate unit 12 including positive electrodes 14, negative electrodes 15 and a lithium electrode 16 provided at the outermost part of the electrode laminate unit 12. The lithium electrode 16 has a lithium-electrode current collector 26 welded to a negative-electrode current collector 22 and a lithium unit 27 sandwiched between the lithium-electrode current collector 26 and the negative electrode 15. The lithium unit 27 is composed of a lithium holding plate 27a that is in contact with the lithium-electrode current collector 26, and a lithium ion source 27b that is provided to the lithium holding plate 27a. The lithium ion source 27b is not mounted on the lithium-electrode current collector 26, but only the lithium-electrode current collector 26 is laminated and welded, whereby the damage of the lithium ion source 27b is prevented, and the manufacturing operation is simplified.
