Abstract
This is to provide an electroconductive polymer material which has excellent adhesion to a base and excellent water resistance. Also, this is to provide a solid electrolytic capacitor which has excellent water resistance by using the same. An electroconductive polymer solution according to the present invention contains an electroconductive polymer, at least one water-soluble multivalent alcohol, and at least one oxoacid having two or more hydroxy groups. Since a resin obtained by carrying out a polycondensation reaction of the water-soluble multivalent alcohol and the oxoacid has a cross-linked structure, an electroconductive polymer having lower water-absorbing property and more excellent water resistance in comparison with a resin having a linear structure can be obtained.
