CAPACITOR AND METHOD OF PRODUCING SAME

摘要

A capacitor includes an anode foil having an anode foil dielectric film deposited thereon by anodic oxidation; an anode lead member including a first metal core with roughness and an anode lead dielectric film deposited on the roughness by anodic oxidation, said anode lead member being electrically connected to the anode foil; a cathode foil opposing to the anode foil interposing a separator between them; a cathode lead member being electrically connected to the cathode foil; and a container filled up with an electrolyte and containing the anode foil, anode lead member, cathode foil and cathode lead member therein. The anodizing voltage employed during anodic oxidation to form the anode lead dielectric film is equal to or higher than about 70% of that used to form the anode foil dielectric film.
