Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an electrode sheet and a method for manufacturing it, wherein the electric resistance between a current-collector foil and an electrode material is reduced while the efficiency of an electric double layer capacitor, etc., is improved. SOLUTION: An electrode material solution 18 a made of graphite electrode material is coated on a current-collector foil 14 with an application part 20 of a manufacturing device 10, and the electrode material solution 18 is dried by a drying part 22. When the current-collector foil 14 coated with the electrode material is rolled with rollers 50a and 50b, the electrode material breaks an aluminum oxide formed on the surface of the current-collector foil 14 and bites into an aluminum layer, resulting in a lower electric resistance between the electrode material and the current-collector foil 14. An electrode sheet 12 is manufactured in this way.
