摘要： A process for producing an electrode for an electric double layer capacitor, in which water is used as a forming auxiliary agent and kneading an pulverizing steps are omitted to improve production efficiency, and a process for producing an electric double layer capacitor employing such a electrode, are provided. In a first mixing step, an activated carbon and a carbon black are mixed by a grinder containing a grinding medium. As the grinder containing a grinding medium used in this first mixing step, a commonly used ball mill can be used. In the second mixing step, a mixture is taken out from the grinder containing a grinding medium of the first mixing step, and moved into a second mixer prepared separately. Then, polytetrafluoroethylene as a binder and water as a liquid lubricant are added and the materials are mixed again. Thereafter, a calendar forming is carried out. The mixture obtained by the second mixing step is not a clumpy body of clay state or rubber state but a product which can be easily turned into grains of 1 to 2 mm, by simple means such as a wire sieve.
