A conductive composition comprises a π conjugated conductive polymer, a dopant, and a nitrogen-containing aromatic cyclic compound. A capacitor comprises an anode composed of a porous material of valve metal, a dielectric layer formed by oxidizing the surface of the anode, and a cathode provided on the dielectric layer and having a solid electrolyte layer containing a π conjugated conductive polymer, which comprises an electron donor compound containing an electron donor element provided between the dielectric layer and the cathode. Another capacitor is based on the above-described capacitor, wherein the solid electrolyte layer further comprises a dopant and a nitrogen-containing aromatic cyclic compound. An antistatic coating material comprises a π conjugated conductive polymer, a solubilizing polymer containing an anion group and/or an electron attractive group, a nitrogen-containing aromatic cyclic compound, and a solvent. An antistatic coating is formed by applying the antistatic coating material.
