Zusammenfassung:	To provide an electric storage device whose negative electrode can be doped with lithium ions in a short time and whose resistance can be lowered. An electric storage device including a unit that is obtained by alternately stacking a positive-electrode sheet 9 and a negative-electrode sheet 10 with a separator 3 interposed therebetween, the positive electrode sheet 9 including a positive-electrode active material layer 1 and a positive-electrode charge collector 4, and the negative electrode sheet 10 including a negative-electrode active material layer 2 and a negative-electrode charge collector 5, in which a foil, an etching foil, or a porous lath foil is used as the positive-electrode charge collector 4 and the negative-electrode charge collector 5, a cut is made in a coating area of the positive-electrode active material layer 1 and the negative-electrode active material layer 2, and a lithium supply source is disposed so as to be opposed to the negative electrode sheet 10 of the unit.
