PURPOSE:To enhance the high-frequency characteristics, reliability etc., by a method wherein, after bonding MnO2 on an oxide film, an electrolytic polymerized film is formed from a polymer solution containing high molecules having carbonic acid group or hydroxyl group. CONSTITUTION:After forming an anode oxide film 3 on a valve metal 1 (Al) selected from tantalum, aluminum, etc., a manganese dioxide (MnO2) 4 is bonded onto the film 3 to form a conductive electrolytic polymer high molecule 5 by applying polymer solution 8 containing high molecules having carbonic acid group or hydroxyl group. The available electrolytic polymerization degree can stably fix anion doped with an electrolytic polymer film in excellent bond properties onto the oxide film 3 as well as enhanced synthesizing properties to reduce the leakage current. It is recommended that the conductive electrolytic polymer high molecules 5 shall by pyrrole, thiophene or other high molecules produced by anode oxidation polymerizing the monomer of the derivatives from pyrrole and thiophene. Through these procedures, the condenser characteristics such as high-frequency characteristics, reliability, etc., can be enhanced. |
