PROBLEM TO BE SOLVED: To obtain an accumulator device that has low internal resistance for an active material layer itself and improved electrical connection between the active material layer and a collector, and has high output characteristics. SOLUTION: An active material formation material 1, containing at least an electrode active material and a binder, is supplied between a lower die 2 and an upper die 3 where irregular patterns 4, 5 mutually formed are arranged opposite, and is pressed with the lower and upper dies to separate the lower and upper dies, thus manufacturing the active material 6 for accumulator devices where irregular patterns 9, 8 are formed on both the rear and on the front surfaces of the active material formation material. The collector 7 is stuck to one surface of the active material made of the active material for accumulator devices, and an electrode 10 for accumulator devices is manufactured, and by using the electrode for accumulator devices, an accumulator device, such as an electric double-layer capacitor, is formed.
