ELECTRICALLY CONDUCTIVE POLYMER SUSPENSION, ELECTRICALLY CONDUCTIVE POLYMER COMPOSITION, SOLID ELECTROLYTE CAPACITOR, AND METHOD FOR PRODUCTION OF THE SOLID ELECTROLYTE CAPACITOR

摘要

Disclosed is an electrically conductive polymer composition having 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 comprises: an electrically conductive polymer material comprising 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.
