Abstract
The invention provides a capacitor electrode member in which layers constituting the electrode member are highly adhesive. The capacitor electrode member comprises aluminum material (), a carbon-containing layer () formed on the surface of the aluminum material (), and further an interposition layer () containing an aluminum element and a carbon element, the interposition layer being formed between the aluminum material () and the carbon-containing layer (). The interposition layer () constitutes a first surface portion which is formed on at least a part of the region of the surface of the aluminum material () and contains a carbide of aluminum. The carbon-containing layer () constitutes a second surface portion () formed so as to extend outward from the first surface portion (). The carbon-containing layer () further contains carbon particles () and the second surface portion () is formed between the first surface portion () and the carbon particles () and contains a carbide of aluminum.
