Abstract
An electric double layer capacitor uses a multi-layer electrode structure, which has a plurality of electrode layers composed of a binder and an electrode material and coated on a current-collecting member, each of the electrode layers including a macromolecular substance. A first electrode layer in contact with the current-collecting member and the second electrode layer in contact with the first electrode layer are formed of different constituents or have different proportions of the same constituent.
