Abstract
A method for producing an electrolytic capacitor includes: preparing an anode foil, a cathode foil, and a fibrous structure, the anode foil having a porous portion including a dielectric layer; preparing a conductive polymer-containing liquid, the conductive polymer-containing liquid containing a conductive polymer component and a first solvent; forming a separator by removing at least a part of the first solvent after applying the conductive polymer-containing liquid to the fibrous structure; forming a capacitor element from the anode foil, the separator, and the cathode foil; and impregnating the capacitor element with an electrolytic solution. An electrical conductivity of the electrolytic solution at 30° C. is 3.0 mS/cm or more.
