1. A conductive composition, comprising:
a conductive polymer (A);
a water-soluble polymer (B); and
a solvent (C1),
wherein the water-soluble polymer (B) comprises a water-soluble polymer (B11) of formula (11), and a water-soluble polymer (B2),
wherein the water-soluble polymer (B2) is present in 0.15% by mass or less, based on total conductive composition mass,
wherein the water-soluble polymer (B11) has formula (11):

OG Complex Work Unit Chemistry
R1 being a linear or branched alkyl group with 6 to 20 carbon atoms, Y1 being a single bond, —S—, —S(═O)—, —C(═O)—O—, or —O—, p1 being an average number of repetitions and is a number in a range of from 1 to 50, and m is a number in a range of from 1 to 5,
wherein the water-soluble polymer (B2) has formula (2);

OG Complex Work Unit Chemistry
each of R4 and R5 independently being a methyl or ethyl group, R6 being a hydrophilic group, R7 being H or a methyl group, Z being a cyano group or a hydroxy group, and q being an average number of repetitions and a number in a range of from 1 to 50,
wherein a (B2)/(B11) ratio, of the water-soluble polymer (B2) to the water-soluble polymer (B11), is less than 9, and
wherein a water/octanol partition coefficient (Log P) for polymerization initiator-derived components in the water-soluble polymer (B) is 8.50 or more.
