An electrically conductive polymer composition contains an electrically conductive polymer obtained by using a polymer in the form of cations composed of repeating structural units of 3,4-ethylene dioxythiophene and polystyrene sulfonic acid as anions and further contains naphthalene sulfonic acid as an additive. A solid electrolytic capacitor 101 or a surface-mount transmission line element 102 has a polypyrrole conductive polymer layer 3 as a first solid electrolyte and a poly(3,4-ethylene dioxythiophene) conductive polymer layer 4 as a second solid electrolyte.
An electrically conductive polymer composition containing an electrically conductive polymer obtained by using a polymer in the form of cations comprising repeating structural units of 3,4-ethylene dioxythiophene given by the following formula 1,
A solid electrolytic capacitor comprising an anode body made of a valve-acting metal, an oxide film formed on a surface of said valve-acting metal, a first solid electrolyte layer formed so as to reach the oxide film inside said valve-acting metal, a second solid electrolyte layer formed at an outer periphery of said first solid electrolyte layer, and a conductor layer formed on said second solid electrolyte layer, wherein said anode body serves as an anode and said conductor layer as a cathode and terminal portions of said anode and cathode are respectively formed, said solid electrolytic capacitor using, as at least one of said first and second solid electrolyte layers, an electrically conductive polymer composition containing an electrically conductive polymer obtained by using a polymer in the form of cations comprising repeating structural units of 3,4-ethylene dioxythiophene given by the following formula 1,
