Abstract: An electrolytic capacitor includes an anode body, a dielectric layer formed on the anode body, a first conductive polymer layer covering at least a part of the dielectric layer, and a second conductive polymer layer covering at least a part of the first conductive polymer layer. The first conductive polymer layer contains a first conductive polymer and a first silane compound. The second conductive polymer layer contains a second conductive polymer and a basic compound. The basic compound may be an amine compound.

Abstract: A method for producing an electrolytic capacitor includes: a first step of preparing an anode body, and forming a dielectric layer on a surface of the anode body; a second step of forming a first conductive polymer layer on a surface of the dielectric layer, the first conductive polymer layer including a first conductive polymer and a first silane compound; a third step of bringing the first conductive polymer layer into contact with a first treatment liquid; and a fourth step of providing a second silane compound to the first conductive polymer layer after the third step.

Abstract: 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.
