An object of the present invention is to provide a method of manufacturing a high capacity lithium ion battery device by safe and simple doping operation. A method of manufacturing a lithium ion battery device comprising a positive electrode and a negative electrode which are laminated with each other, wherein an active material used on the positive electrode is a sulfur-based active material having a total sulfur content of not less than 50% by mass measured by an elementary analysis, the method comprising: a step of forming through-holes penetrating in a thickness direction of the positive electrodes and the negative electrodes, a step of laminating the positive electrodes with the negative electrode and disposing a lithium ion feeding source on at least one side of a laminating direction, and a step of allowing lithium derived from the lithium ion feeding source to be carried on the positive electrode and the negative electrode.
