Abstract
An electrolytic capacitor includes an anode body, a dielectric layer disposed on the anode body, and a solid electrolyte layer disposed on the dielectric layer. The solid electrolyte layer includes a first layer and a second layer disposed on the first layer. The first layer contains a first conductive polymer. And the second layer contains a second conductive polymer that is a self-doped conductive polymer.

An electrolytic capacitor comprising:
- an anode body;
- a dielectric layer disposed on the anode body;
- and
- a solid electrolyte layer disposed on the dielectric layer, wherein:
- the solid electrolyte layer includes a first layer and a second layer disposed on the first layer, the first layer containing a first conductive polymer, the second layer containing a second conductive polymer that is a self-doped conductive polymer, and
- the first layer has voids in which the second conductive polymer exists.

A method for producing an electrolytic capacitor comprising:
- preparing an anode body on which a dielectric layer is disposed;
- and
- forming a solid electrolyte layer on the dielectric layer, wherein:
- the forming of the solid electrolyte layer includes:
- forming a first layer containing a first conductive polymer by polymerizing a precursor of the first conductive polymer, the first layer having voids;
- and
- forming a second layer containing a second conductive polymer on the first layer by adhering a liquid composition containing the second conductive polymer to the first layer so that the second conductive polymer enters in the voids of the first layer, the second conductive polymer being a self-doped conductive polymer.
