Abstract

Provided are a conductive polymer-containing dispersion for obtaining a solid electrolytic capacitor with low equivalent series resistance (ESR) while maintaining the capacitance, a method for producing same, and a solid electrolytic capacitor having low ESR while maintaining the capacitance. A conductive polymer-containing dispersion comprising a conjugated conductive polymer (A), a polyanion (B), an additive (C), and a dispersion medium (D), wherein a hydrogen bond term δHof the additive (C) as a Hansen solubility parameter is 5.0 to 20.0 MPa.
