れない。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an electrolytic cell for depositing an electrochromic material by electrolytic polymerization on the surface of a conductive film layered on the surface of a transparent insulating substrate. Electrochromic (EC) membranes undergo a reduction or oxidation effect depending on the polarity of the applied voltage, resulting in coloring or decolorization, and then the applied voltage is cut off. It also has a memory function that maintains that state. There are two types of EC films: inorganic and organic. For the former, vacuum evaporation or sputtering is the mainstream, but the materials, such as iridium, are expensive, and the equipment is large to cover a large area. In order to achieve this goal, high costs are unavoidable.
一方、電解重合により製膜される有機系は現在のところ
無機系に比べ安定性で劣るが、材料が安価であるために
大面植化に有利である。On the other hand, organic films formed by electrolytic polymerization are currently inferior in stability to inorganic films, but are advantageous for large-scale planting because the materials are inexpensive.

により製膜している。In this case 1, for example, to manufacture a transmission type ECII'W for light control glass, a conductive film is formed as thinly as possible on a transmission type insulating base material such as glass or a transparent film so as not to impair transparency, and the surface When depositing EC%l, a conventional electrode device was used as shown in FIG. That is,
'In an electrolytic bath l containing cardiac analysis fluid, a transparent insulating base material 2 on which a conductive film is formed and a counter electrode 3 are placed opposite each other,
By connecting a constant current source 4 between the conductive film and the counter electrode 3, the film is formed by electrolytic oxidative polymerization like polyaniline or polypyrrole.
しかしながら、導電膜はなるべく薄くされるために電極

やしたとしても、いずれにしろ大面積化されると中心部
分の製膜は薄くか又は不可能になる。However, because the conductive film is made as thin as possible, a voltage drop gradually occurs in the conductive film away from the electrode contact, making it difficult to ensure a uniform current density. However, if the area is increased, the film formation in the central portion becomes thin or impossible.

流密度が均一になる。[Means and effects for solving the problem] In order to achieve this object, the present invention uses a conductive plate having holes in a plurality of dispersed locations as one electrode of the pair, and the other electrode has holes in each of the electrodes. The holes were formed by fitting insulators into the holes and inserting conductive needles into each insulator. Since the conductive needles running as the other electrode are distributed and contacted with the conductive film, the current density of the four-electrode film becomes uniform over the entire area.

製膜の光学特性にもほとんど影響しない。When forming the film, a constant electric current fi, one pole of [19] is connected to the conductive plate 12.
The electrodes are connected in parallel to the rear end of the conductive needle 22 of each electrode 20. Further, the area from this rear end to the electrode is insulated. As a result, the conductive film 17 is supplied with power in a uniformly distributed manner, and is not affected by voltage drop depending on the position, so that the EC film is uniformly deposited over the entire area. Since the conductive needle 22 is almost surrounded by the insulator 21, the amount of current is effectively utilized for the #A film, and the conductive film! Since the contact area of the conductive needle 22 with the conductive needle 7 is also small, it hardly affects the optical properties of the film formation.
