An electrolytic capacitor includes: an anode body; a dielectric layer formed on the anode body; a first conductive polymer layer which covers at least a portion of the dielectric layer; and a second conductive polymer layer which covers at least a portion of the first conductive polymer layer. The first conductive polymer layer includes a first layer and a second layer. The first layer contains a first conductive polymer and a first dopant, and covers at least a portion of the dielectric layer. The second layer is formed on the first layer, and contains a first silane compound. The second conductive polymer layer contains a second conductive polymer, a second dopant, and a basic compound.
