Abstract: A method for producing an electrode for electric double layer capacitors is disclosed which includes: a step of mixing a particulate elastomer and a carbonaceous material with each other in a powdery form, thereby obtaining a powdery mixture; and a step of dry-forming the resultant powdery mixture, thereby forming an electrode layer. With this method, an electrode which enables to form a high-capacity electric double layer capacitor can be produced by simplified steps with high productivity.
