Solid electrolytic capacitor and method of manufacturing thereof

摘要

A solid electrolytic capacitor with suppressed occurrence of short circuit is provided. The solid electrolytic capacitor (100) includes an anode body (11) having a surface on which a dielectric film (12) is formed, and a conductive polymer layer (13) formed on the dielectric film (12). The conductive polymer layer (13) includes at least a first conductive polymer layer (13A) formed on the dielectric film (12) and a second conductive polymer layer (13B) formed on the first conductive polymer layer (13A). A silane compound in the first conductive polymer layer (13A) and the silane compound in the second conductive polymer layer (13B) have respective concentrations different from each other.
