Abstract:
1. A method of manufacturing a solid electrolytic capacitor comprising a surface-roughened flat plate-shaped metal base, an anodic oxide film formed by anodic oxidation on a surface of the metal base, a solid electrolyte layer formed of a conductive polymer at at least a portion on the anodic oxide film, a cathode electrode portion formed on the solid electrolyte layer, and an anode electrode portion formed at a portion, where the solid electrolyte layer is not provided, of the metal base, the method comprising: coating a conductive paste on the anodic oxide film on one side of the metal base and curing the conductive paste coated, thereby forming a metal layer; and irradiating a laser beam from a side, opposite to the one side where the conductive paste is coated, of the metal base to weld together the metal base and the metal layer, thereby forming the anode electrode portion.
