摘要：Provided are an electrolytic capacitor with high withstand voltage capable ofpreventing deterioration of withstand voltage characteristics caused by lead-free reflowor the like and improving ESR characteristics, and a manufacturing method thereof. Theelectrolytic capacitor is obtained by impregnating a capacitor element in which an anodeelectrode foil and a cathode electrode foil are wound with a separator interposed, with adispersion containing: particles of a conductive polymer; sorbitol or sorbitol and

polyalcohol; and a solvent so as to form a solid electrolyte layer containing 60 to 92 wt%of the sorbitol or the sorbitol and polyalcohol, and by filling an electrolytic solutioncontaining ethylene glycol in a gap portion in the capacitor element on which the solidelectrolyte layer is formed.
