Abstract
A conductive composition may include a conductive polymer (A), a water-soluble polymer (B), and a solvent (C1). The water-soluble polymer (B) may include a water-soluble polymer (B11) of formula (11), and a water-soluble polymer (B2) of formula (2) as the water-soluble polymer (B) of 0.15% by mass or less, based on a total mass of the conductive composition: wherein Ris a linear or branched alkyl group with 6 to 20 carbon atoms, each of Rand Ris independently a methyl or ethyl group, Ris a hydrophilic group, Ris H or a methyl group, Yis a single bond, —S—, —S(═O)—, —C(═O)—O—, or —O—, Z is a cyano group or a hydroxy group, each of p1 and q is an average number of repetitions, and is a number of from 1 to 50, and m is a number of from 1 to 5.
