ABSTRACT:
The present invention provides a binder for an electric double layer capacitor comprising; a polymer (A) containing an acrylate monomer unit, and having two or more glass transition temperatures; a composition for the electric double layer capacitor containing this binder and an active material for an electrode; an electrode for the electric double layer capacitor in which this composition is layered on a current collector, so as to exhibit excellent heat resistance and flexibility and a high binding force between the active material for the electrode and the current collector; and an electric double layer capacitor comprising this electrode, so as to exhibit a large electrostatic capacity and a small internal resistance.
