摘要： Sub pits are suppressed from branching in a surface layer of an aluminum foil, and an electrode foil for an aluminum electrolytic capacitor with a large electrostatic capacitance and a method of manufacturing the same are provided. A large number of main pits are formed by etching on both surfaces of the aluminum foil to extend from the surfaces in a thickness direction of the foil, sub pits are formed to branch away from the main pits for a range from a vicinity of a surface layer portion of each main pits excluding the surface layer portion, to inner ends of the main pits. Since the sub pits are not formed in the surface layer of the aluminum foil, the sub pits can be increased in density effectively to the electrostatic capacitance, allowing the electrode foil for the aluminum electrolytic capacitor to have high mechanical strength and high electrostatic capacitance.

摘要： A method of manufacturing a positive electrode foil of an aluminum electrolytic capacitor is provided in which anodizing conditions are optimally determined and automatically set to minimize the loss of production and to produce a constant quality of the positive electrode foil. The method comprises an etching process and an anodizing process. An etched foil produced in the etching process is subjected to a constant current inspection, and then, the anodizing conditions are determined from the result of the constant current inspection. The anodizing conditions are transferred to a control panel in the anodizing process where they are automatically registered as its settings. Also, an apparatus for manufacturing the positive electrode foil is provided which has a voltage sensor connected between an output running roller and cathode electrodes in an anodizing tank. A voltage measured by the voltage sensor is fed back to a direct-current source for controlling its output voltage.
