摘要： A wound electric double-layer capacitor suppresses electrochemical reaction on polarized electrode layers, reduces characteristic degradation, and has high reliability. The capacitor has a capacitor element formed by winding positive and negative electrodes with a separator interposed between them, a metal case for storing the capacitor element and an electrolyte for driving, and a sealing member for sealing an opening of the metal case. In the positive and negative electrodes, positive and negative electrode lead wires are coupled to exposed parts of current collectors having polarized electrode layers on their both surfaces, respectively. The negative electrode is wound at least one extra turn from the winding end of the positive electrode of the capacitor element, and hence a part where the polarized electrode layers formed in the negative electrode face each other through the separator is formed on the outermost periphery of the capacitor element.

摘要： In an electric double-layer capacitor, resistance of a polarizable electrode layer is reduced and gas generation inside a case is suppressed in an attempt to improve reliability. On that account, an electric double-layer capacitor is provided, which is obtained by housing in a case, together with a driving electrolyte, a capacitor element wound with a separator interposed between electrodes being paired anode and cathode electrodes in each of which polarizable electrode layers are formed on and lead wires are fixed to both sides of a current collector made of metallic foil, such that the polarizable electrode layers are opposed to each other. Further, an electric double-layer capacitor is provided in which the lead wire is fixed to a polarizable-electrode-layer-removed section on the electrode where the polarizable electrode layer has been removed, and an area of the polarizable-electrode-layer-removed section is not smaller than 1 and not larger than 2.0 when a project area of a portion where the lead wire is connected with the current collector is set to 1.
