Abstract
Provided are an electrode structure capable of suppressing a leakage current, having a high capacitance, allowing an electrical short circuit caused through contact with an electrolyte to be suppressed, and operable to be applied as an anode of a capacitor; a method for manufacturing the electrode structure; and a capacitor including the electrode structure. The method for manufacturing the electrode structure includes: a covering layer formation step of forming on a surface of an aluminum material a covering layer of a dielectric precursor including valve metal; and a reduction heating step of heating in a reducing atmosphere including no carbon the aluminum material having the covering layer formed thereon. The electrode structure includes: an aluminum material; a covering layer being formed on a surface of the aluminum material, including valve metal, and having an electrically conductive portion; and an interposing layer being formed between the aluminum material and the covering layer and including aluminum and oxygen.
