Patent attributes
An electrically conductive polymer composition has high electrical conductivity, excellent water resistance, high density, and excellent smoothness. Also disclosed is a solid electrolyte capacitor which is prevented from the reduction in electrical conductivity, has low ESR, and also has excellent reliability. Further disclosed is a method for producing the solid electrolyte capacitor. The electrically conductive polymer composition is produced by removing a dispersion medium from an electrically conductive polymer suspension, wherein the electrically conductive polymer suspension includes: an electrically conductive polymer material including a dopant composed of a polyacid or a salt thereof and an electrically conductive polymer; at least one compound (A) selected from erythritol, xylitol and pentaerythritol; and the dispersion medium.
