Claim 13:
14. A method for producing an electrolytic capacitor, the method comprising the steps of:
preparing a sheet-like member that constitute a capacitor element;
preparing a first conductive polymer dispersion liquid that contains a first conductive polymer component and a first dispersion medium, wherein the first conductive polymer component is contained in an amount of 3 mass % or more and 15 mass % or less, and the first conductive polymer dispersion liquid has a viscosity of 100 mPa·s or more, the viscosity being measured at room temperature by using a vibration viscometer;
forming a conductive polymer layer that contains the first conductive polymer component by applying the first conductive polymer dispersion liquid to the sheet-like member by using a coating method and then removing at least a portion of the first dispersion medium; and
producing a capacitor element by using the sheet-like member on which the conductive polymer layer has been formed,
wherein a mass of the first conductive polymer component per unit area of the sheet-like member is 0.02 mg/cm2 or more.
