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 (1), a carbon-containing layer (2) formed on the surface of the aluminum material (1), and further an interposition layer (3) containing an aluminum element and a carbon element, the interposition layer being formed between the aluminum material (1) and the carbon-containing layer (2). The interposition layer (3) constitutes a first surface portion which is formed on at least a part of the region of the surface ofthe aluminum material (1) and contains a carbide of aluminum. The carbon-containing layer (2) constitutes a second surface portion (21) formed so as to extend outward from the first surface portion (3). The carbon-containing layer (2) further contains carbon particles (22) and the second surface portion (21) is formed between the first surface portion (3) and the carbon particles (22) and contains a carbide of aluminum.
