Abstract
Provided is a solid electrolytic capacitor with low ESR (equivalent series resistance) and excellent reliability during high-temperature storage. The solid electrolytic capacitor includes an anode formed of a valve metal, a dielectric film provided on the anode, a conducting polymer layer provided on the dielectric layer, and a cathode extraction layer provided on the conducting polymer layer. The conducting polymer layer contains a metal-based conductive filler in at least one of a flake form and a fiber form.
