Abstract: A composite metal material (1), used, e.g., as an electrolytic capacitor electrode-use material, comprising a polymer thin film (11) formed by self-organizing on at least one surface of a metal material substrate (10) and having fine patterns (12). This polymer thin film (11) is formed, for example, by drying the hydrophobic organic solvent solution of a polymer compound. Etching this composite metal material (1) forms etching pits distributed uniformly at high density based on the above fine patterns.
