PROBLEM TO BE SOLVED: To provide a conductive polymer dispersion liquid which has excellent stability as a dispersion liquid and can easily form a conductive coating film with high conductivity and high reliability (particularly, reliability under high temperature environment).SOLUTION: A conductive polymer dispersion liquid comprises a &pgr;-conjugated conductive polymer, a polyanion, a sulfonic acid ester represented by chemical formula (1), and a dispersion medium. The chemical formula (1) is: R(SOR), where Rand Rindependently represent a substituent, and n is an integer of 1 or more. |
