Claim 4:
5. A method for manufacturing a solid electrolytic capacitor having a configuration including an anode foil having formed thereon an oxide film, a cathode foil, a separator disposed between the anode foil and the cathode foil, and a solid electrolyte,
comprising
forming the solid electrolyte in a gap between the anode foil and the cathode foil with a dispersing liquid containing an electroconductive polymer compound in a fine particle form and glycerin as a first water-soluble compound, and
then introducing a water-soluble compound solution containing one kind or multiple kinds of polyethylene glycol or diethylene glycol as a glycol compound in a liquid form as a second water-soluble compound to surround the formed solid electrolyte,
the second water-soluble compound having an average molecular weight of less than 400, and
the water-soluble compound solution contains water in an amount of 0.5 wt % or more.
