摘要： Provided are an electrolytic capacitor with high withstand voltage capable of preventing deterioration of withstand voltage characteristics caused by lead-free reflow or the like and improving ESR characteristics, and a manufacturing method thereof. The electrolytic capacitor is obtained by impregnating a capacitor element in which an anode electrode foil and a cathode electrode foil are wound with a separator interposed, with a dispersion 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 solution containing ethylene glycol in a gap portion in the capacitor element on which the solid electrolyte layer is formed.

摘要： A high voltage proof solid electrolytic capacitor that can prevent deterioration of voltage proof property due to lead-free reflow etc. and a manufacturing method thereof are provided. A capacitor element having an anode and cathode electrode foils wound via a separator is impregnated with a dispersion comprising conductive polymer particles or powder and a solvent to form a solid electrolyte layer consisting of a conductive polymer, and the voids inside the capacitor element having the solid electrolyte layer formed are filled with an ion-conducting substance comprising a mixed solvent comprising ethylene glycol and γ-butyrolactone together with a solute selected from at least one type of an ammonium salt, a quaternary ammonium salt, a quaternized amidinium salt, and an amine salt of an organic acid, an inorganic acid, and a composite compound between organic acid and inorganic acids to obtain a solid electrolytic capacitor.
