Abstract

Provided is an electroconductive polymer composition with a good film forming property and a high electroconductivity. Also, provided is an electroconductive polymer material and an electroconductive substrate with a high electroconductivity and transparency. Further, provided is a solid electrolytic capacitor with a high capacity and a low ESR. Disclosed is an electroconductive polymer composition, containing an electroconductive polymer obtained by an oxidation polymerization by using an oxidant in a reaction solution which contains at least one monomer selected from the group consisting of pyrrole, thiophene and derivatives thereof, a polyacid or a salt thereof as a dopant, and a solvent containing water and an aprotic solvent.
