ELECTRODE FOR ELECTRIC STORAGE DEVICE, AND METHOD OF MANUFACTURING THE SAME, ELECTRIC STORAGE DEVICE ELEMENT, AND LITHIUM ION CAPACITOR

PROBLEM TO BE SOLVED: To provide an electrode for an electric storage device which can achieve a large capacitance and high reliability even when a plurality of through holes are formed through a collector, and active material layers are formed on both surfaces of the collector, to provide a method of manufacturing the same, and to provide an electric storage device element and a lithium ion capacitor which exhibit excellent performance and high productivity. SOLUTION: The electrode for the electric storage device includes a porous collector, a first active material layer formed on one surface of the porous collector, and a second active material layer formed on the other surface of the porous collector. An inner circumferential surface of at least one through hole of the plurality of through holes of the porous collector is covered with the second active material layer. The first active material layer blocks at least one through hole of the plurality of through holes of the porous collector on one surface side of the porous collector, and includes a projection protruding in one surface side direction of the porous collector in a position corresponding to the through hole.
