    Abstract: A method of manufacturing a solid electrolytic capacitor including a porous anode body made of a valve metal having a dielectric film on a surface thereof, and a solid electrolyte layer disposed on a surface of the dielectric film. The method including: a step of; in a liquid including a polyanion and an aqueous medium, polymerizing a monomer compound to obtain a dispersion (1) containing a conjugated electrically conductive polymer and subjecting dispersion treatment to the dispersion (1) to obtain a dispersion (2) containing the conjugated electrically conductive polymer; depositing the dispersion (2) to a porous anode body made of a valve metal having a dielectric coating on a surface thereof; and removing the aqueous medium from the dispersion (2) deposited on the porous anode body to form a solid electrolyte layer, wherein an operation which pauses the dispersion treatment is performed.

    Abstract: A method for producing a conductive polymer-containing dispersion, the method including a polymerization step of subjecting a monomer that is to be a constitutional unit of a conjugated conductive polymer to a polymerization reaction in a mixed solution containing the monomer, a polyanion, and a dispersion medium to produce a polymerized product; and a dispersion treatment step of performing a dispersion treatment on a reaction solution obtained in the polymerization step to prepare a dispersion of the polymerized product, wherein a dispersion medium is added one or more times at any point in time from after the polymerization step to during the dispersion treatment step to make a mass concentration (B) of the polymerized product in the dispersion after the dispersion treatment step lower than a mass concentration (A) of the polymerized product in the reaction solution.
