PROBLEM TO BE SOLVED: To provide a solid-state electrolytic capacitor of high capacity and low ESR, relating to the solid-state electrolytic capacitor obtained by forming a conductive high polymer layer in a capacitor element by using a dispersed solution of conductive high polymer.SOLUTION: In the solid-state electrolytic capacitor, an anode body composed of a valve metal, and, on the surface of the anode body, a dielectric oxide film layer, a solid-state electrolyte layer, and a cathode layer are formed sequentially. Since the anode body is impregnated with the dispersed solution of the conductive high polymer wherein dispersing treatment is performed by ultra-high pressure treatment to form a solid-state electrolyte, dispersion of the dispersed solution of the conductive high polymer is raised, and the dispersed particles of the conductive high polymer are accumulated on the surface of the anode to form the solid-state electrolyte, thereby ESR is reduced probably due to uniform solid-state electrolyte formation. |
