Provided are: an electrolytic capacitor having excellent heat resistance and a method for producing the same; a conductive composition that can form the electrolytic capacitor, and a method for producing the same; and a dopant solution and a monomer solution which are for producing the conductive composition. The dopant solution for a conductive polymer according to the present invention is characterized by being obtained by dissolving a dopant for a conductive polymer in a solvent, wherein: the dopant for a conductive polymer contains a salt (A) of a sulfonic acid that has an anthraquinone skeleton, and a compound that has an alkylamine having a specific structure, an alkanolamine having a specific structure, an alkylamine having a specific structure, or a heterocyclic ring having 1-3 nitrogen atoms in a ring; and the solvent contains water or a lower alcohol.
