More Information
Summary:A solid electrolytic capacitor element includes an anode body, a dielectric layer formed on a surface of the anode body, and a cathode part covering at least a part of the dielectric layer. The cathode part includes a solid electrolyte layer covering the at least the part of the dielectric layer. The solid electrolyte layer includes a conductive polymer component containing a conjugated polymer. An oxygen permeability P1 of the solid electrolyte layer after heating at 230° C. for 5 hours is less than or equal to 1.0 cm3/m2·24 h·atm.
