SOLID ELECTROLYTIC CAPACITOR AND MANUFACTURING METHOD THEREOF

摘要

Provided is a solid electrolytic capacitor with excellent ESR characteristics at high temperatures, and a manufacturing method thereof. Using a conductive polymer dispersion obtained by dispersing particles of a conductive polymer in a solvent, a solid electrolyte layer is formed on a capacitor element comprising a positive electrode foil and a negative electrode foil wound with a separator interposed therebetween, and an electrolytic solution which contains the ammonium salt of an aromatic carboxylic acid as a solute is filled in a gap portion inside of the capacitor element on which the solid electrolytic layer was formed, thereby configuring the solid electrolytic capacitor.
