See full text

A solid electrolyte capacitor includes an anode foil on a surface of which an oxide film is formed, a cathode foil, and a separator. A gap between the anode foil and the cathode foil is filled with a solid electrolyte which contains a conductive fine particles containing a conductive polymer compound and a hydrophilic polymer compound. The hydrophilic polymer compound has a structure expressed by a following chemical formula (I) and a structure expressed by a following chemical formula (II).
