ELECTRODE FILM, ELECTRODE AND METHOD OF MANUFACTURING THE SAME, AND ELECTRIC STORAGE DEVICE

PROBLEM TO BE SOLVED: To provide an electrode film having high conductivity, and to provide an electrode and an electric storage device using the same. SOLUTION: The electrode film includes an active material having particle sizes of 2 μm or larger and 50 μm or smaller, and conductive ion containing inorganic particles having particle sizes of 1 nm or larger and smaller than 2 μm, the active material being bonded thereto via the conductive ion containing inorganic particles. The electrode includes the electrode film laminated on a collector. The electric storage device includes the two electrodes arranged so that the electrode films are opposed to each other. In the electric storage device, both electrodes are rolled or laminated in the state that a separator exists between the electrode films, and the electrodes and the separator are filled in a metal case together with electrolytic solution.
