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