Abstract
A method for producing an electrolytic capacitor, the method including steps of: preparing an electrode foil; preparing a first conductive polymer dispersion containing a first conductive polymer component and a first dispersion medium; forming a first conductive polymer layer containing the first conductive polymer component, by applying the first conductive polymer dispersion to a surface of the electrode foil by a coating method, and then at least partially removing the first dispersion medium; and fabricating a capacitor element, using the electrode foil having the first conductive polymer layer.
