METHOD FOR MANUFACTURING SOLID ELECTROLYTIC CAPACITOR

The present invention provides a method for manufacturing a solid electrolytic capacitor having: a step (A) for polymerizing a monomer for obtaining a conjugated electroconductive polymer in a dispersion medium containing seed particles which have been formed into protective colloids by means of polyanions or a dispersion medium containing polyanions, and obtaining a conjugated electroconductive polymer-containing dispersion; a step (B) for adding a morpholine compound to the conjugated electroconductive polymer-containing dispersion and preparing a dispersion containing the morpholine compound and the conjugated electroconductive polymer; a step (C) for having the dispersion adhere to a porous positive electrode body comprising a valve action metal having a dielectric coating film on thesurface thereof; and a step (D) for removing the dispersion medium from the dispersion containing the morpholine compound and the conjugated electroconductive polymer adhering to the porous positive electrode body and forming
