PURPOSE:To obtain a dimmer which has improved coloring and discoloring responsiveness has a large area, by placing a transparent substrate formed with linear materials consisting essentially of carbon on a transparent electrode and a transparent substrate formed with an electrochromic (EC) layer on the transparent electrode so as to face each other. CONSTITUTION:Transparent electrodes 1, 4 are formed on transparent substrate (glass, plastic sheets, etc.) 3, 6, whereafter sheets 5 of about 1mm. width which consist essentially of carbon and transition metal compds. such as MnO2 and are produced by mixing resins such as tetrafluoroethylene or the like and molding the mixture are adhered by means of conductive paste on the substrate 6 on the rear side at about 1cm line intervals. An EC layer 2 of WO3, MoO3 or the like is formed on the electrode 1 of the substrate 3 on the front side, and an electrolyte 7 is put in between both substrates 3, 6. The substrates are sealed 8, whereby a dimmer is made. Or linear metallic electrodes may be provided on the rear substrate and the surfaces thereof may be coated with the above-described materials contg. carbon. The bodies 5 are in conspicuous and the EC layer colors when applied with the voltage. If the reverse voltage is applied, there is no need for applying the voltage continuously until the EC layer is made colorless, thus the large sized dimmer having good coloring and discoloring responsiveness is easily obtained with low electric power consumption.
