Abstract
A gel electrolytic capacitor that can further improve withstand voltage is provided. The gel electrolytic capacitor includes: an anode foil; a cathode foil; and a gel electrolyte disposed between the anode foil and the cathode foil. The gel electrolyte consists of a polymer having three-dimensional (3D) network structure and an electrolyte solution held in said polymer. The polymer is formed by polymerizing 2-hydroxyethyl methacrylate or methacrylic acid. The electrolyte solution includes amines or quaternary cyclic amidinium.
