PURPOSE:To prevent generated air bubbles from entering a thin film when the thin film is formed by electrodeposition with an aqueous suspension of a polyelectrolyte, by specifying the structure of an electrode itself or the electrodeposition surface of non-electrode. CONSTITUTION:A thin film is electrochemically formed on an electrodeposition surface with an aqueous suspension of a polyelectrolyte such as collagen or casein. At this time, both electrodes, cathode and anode, are formed with an electrically conductive porous substance such as a sintered metal or a metallic mesh, and the electrodeposition surfaces of non-electrode is formed with an electrically nonconductive porous substance such as biscuit or ceramics and an electrically conductive substance. The aqueous suspension is filled into an electrodeposition cell provided with the electrodes and the electrodeposition surface of non-electrode, and DC voltage is applied between the electrodes to form a thin film on the prescribed electrode surface and electrodeposition surface of non-electrode. Thus, generated air bubbles are prevented from entering the electrodeposited thin film and the formed thin film can be easily stripped from the electrodeposition surface.
