CONDUCTIVE POLYMER SOLUTION AND APPLICATION OF SAME

原文（中国語）

Provided is an electrically conductive polymer solution which can provide an electrolytic capacitor having a high capacity and exhibiting a low ESR characteristic. An electrically conductive polymer solution is used which contains: 0.01 to 10% by mass of polythiophene (A) including at least one structural unit selected from the group consisting of a structural unit represented by a general formula (1) below and a structural unit represented by a general formula (2) below; 0.001 to 20% by mass of an epoxy compound (B) having at least two epoxy groups; and water, and in which a pH is 1.5 to 5.0, where Rrepresents a hydrogen atom, a methyl group, an ethyl group, a linear or branched alkyl group having 3 to 6 carbon atoms, or a fluorine atom, m represents an integer of 1 to 10, and n represents 0 or 1.
