Abstract: An electrolytic capacitor includes a capacitor element containing a conductive polymer and a liquid component. The liquid component includes a first anion component and a second anion component. The first anion component has a carbonyloxy bond. The second anion component has no carbonyloxy bond and has a sulfonylimide bond.

Abstract: An electrolytic capacitor includes a capacitor element and a liquid component. The capacitor element includes an anode body including a dielectric layer on a surface of the anode body, and a solid electrolyte layer covering at least a part of a surface of the dielectric layer. The solid electrolyte layer contains a conductive polymer component, and the liquid component contains a first polymer component. The first polymer component includes a carbon chain whose main chain does not contain a heteroatom at a position other than a terminal of the main chain. Units constituting the first polymer component include at least one first unit selected from the group consisting of a (meth)acrylic acid-based unit having a carboxy group and a vinyl alcohol-based unit having a hydroxy group. A proportion of the at least one first unit in an entirety of the units constituting the first polymer component is more than 50 mass %.

Abstract: An electrolytic capacitor includes a capacitor element. The capacitor element includes an anode body and an electrolyte layer. The anode body has a dielectric layer on a surface of the anode body. The electrolyte layer is disposed to be adjacent to the dielectric layer. The electrolyte layer contains a first conductive polymer and a non-aqueous solvent. The first conductive polymer is a self-doped conductive polymer.
