MANUFACTURING METHOD FOR ELECTRODE FOIL FOR CAPACITOR, ELECTRODE FOIL FOR CAPACITOR, STACKED ELECTROLYTIC CAPACITOR, AND WINDING-TYPE ELECTROLYTIC CAPACITOR

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method for an electrode foil for a capacitor that can surely decrease electrical connection resistance between the electrode foil's collector and a terminal component.;SOLUTION: An electrode foil for a capacitor has a power accumulator and a collector to which a terminal component is electrically connected. The manufacturing method for this electrode foil includes a masking step 100 that continuously masks at least a first surface and a second surface of one side edge of a belt-like electrode foil material each along the side edge at a specified width, an etching step 101 that applies an etching treatment to an unmasked part of the electrode foil material after the masking step is completed to use the unmasked part of the electrode foil material as a power accumulator, and a masking agents removing step 104 that removes masking agents of the electrode foil material's masked part after the etching step 101 to use as a collector the part from which the masking agents of the electrode foil material are removed.;COPYRIGHT: (C)2006,JPO&NCIPI
