Title: Solid electrolytic capacitor and method for manufacturing the same

Abstract: Provided is a solid electrolytic capacitor with a high capacity occurrence rate and a high capacity and a method for manufacturing the solid electrolytic capacitor. An anode body is formed on a periphery of an anode lead having a hollow structure. The anode body has a porous body of a valve metal or an alloy of the metal as its main component. The hollow structure allows an inside and an outside of the anode body to connect with each other. A dielectric layer is formed on a surface of the anode body, and a conducting polymer layer is formed on a surface of the dielectric layer. When the conducting polymer layer is formed, the inside of the anode body is depressurized by suction from the outside of the anode body through the hollow structure of the anode lead.
