Abstract
The invention relates to an electrodeposition method for forming a film of an electrochemically synthesizable and functional substance, e.g. Prussian blue useful as an electrochromic material, on an electrode plate having a conductive coating film relatively high in surface resistivity such as a tin dioxide or indium trioxide film. A desired film of uniform thickness can be formed even when the electrode plate is as large as 40 cm square or is still larger by providing the electrode plate with an elongate auxiliary electrode element formed of, for example, a metal wire or foil, which is attached to the outer surface of the conductive coating film so as to extend at least along the whole periphery of the electrode plate.
