Abstract

A solid electrolytic capacitor includes a solid electrolytic capacitor element having an anode element having a dielectric film formed on a surface thereof and a conductive polymer layer formed on the anode element, an ionic liquid composed of an anion component and a cation component is present in the conductive polymer layer, and the cation component contains a cation having two or more ether linkages.

Claims (4)

1. A solid electrolytic capacitor, comprising a capacitor element which has an anode element having a dielectric film formed on a surface thereof and a conductive polymer layer formed on said anode element and including a conductive polymer,

an ionic liquid composed of an anion component and a cation component being present in said conductive polymer layer and being a salt molten and kept in a liquid state in an environment at room temperature, and

said cation component being a cation having methoxyethoxyethyl group.

2. The solid electrolytic capacitor according to claim 1 , wherein said cation component is ammonium ion.
