Abstract
A connecting structure of a lead wire is electrically connected to an electrode in which a polarized electrode layer is formed on a surface of a current collector plate. A region of the electrode, to which the lead wire is to be joined, is free from the polarized electrode layer. The lead wire is joined to the current collector plate by means of stitching and then compressed thereto. This connecting structure may keep a capacitance of a capacitor and improve contact reliability. An electric double layer capacitor having the structure and a method for manufacturing the capacitor are also provided.
