Abstract
An electrode holder and a method for producing an electrode for an aluminum electrolytic capacitor are provided that enable prevention of exfoliation of a porous layer during chemical formation even when the porous layer is formed on an aluminum electrode so as to have a thickness of 200 micrometers or greater. When an aluminum electrodehaving at least one surfaceon which a porous layerhaving a thickness of 200 micrometers or greater is formed is subjected to chemical formation in a chemical formation solution, the aluminum electrodeis held by an electrode holder. The electrode holderincludes: an insulating first support plateconfigured to overlap the one surfaceof the aluminum electrode; an insulating second support plateconfigured to overlap the other surfaceof the aluminum electrode; and a connecting partconfigured to connect the first support plateand the second support plateto each other. A portion of the first support platethat overlaps the porous layerwhile being in contact therewith is formed with a porous member
