<p><P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a solid electrolytic capacitor in which stress applied to a solid electrolyte layer due to thermal stress and mechanical stress is reduced to suppress an increase in an ESR. <P>SOLUTION: The method for manufacturing a solid electrolytic capacitor includes steps of: successively forming a dielectric layer 2 and a solid electrolytic layer 3 on an anode body 1 made of a valve metal; and forming a carbon layer 4 on the solid electrolytic layer 3, wherein the carbon layer 4 is formed by adhering a carbon solution to the solid electrolytic layer 3 and drying the carbon solution, wherein the carbon solution contains an electrically conductive carbon, a binder resin, and a solvent and the total solid concentration of solids of the electrically conductive carbon and the binder resin in the carbon solution is 36% by weight or more and 52% by weight or less. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
