Abstract
A method of manufacturing a solid electrolytic capacitor includes the steps of forming an anode element by sintering powders of a valve metal, washing the anode element with a first wash solution, forming a dielectric film on the anode element after the washing step, and forming a solid electrolytic layer on the dielectric film. The first wash solution is an aqueous solution containing ammonia and hydrogen peroxide.
