The invention discloses a method for manufacturing a chip type organic solid electrolyte electrolytic capacitor. The method comprises the steps of preparing an anode body; preparing a dielectric oxidation film; and preparing a polymer cathode structure. The method is characterized in that the cathode of the chip type organic solid electrolyte electrolytic capacitor is obtained by employing an electrostatic self-assembling method; and by alternately assembling polyelectrolyte with reverse charges on the surface of the dielectric oxidation film in a solution, an electroconductive polymer composite polyelectrolyte is further stably structured as a cathode film of the chip type organic solid electrolyte electrolytic capacitor. By employing the manufacturing method provided by the invention, the obtained chip type organic solid electrolyte electrolytic capacitor has the characteristics of low equivalent series resistance and favorable voltage withstand property. The method can be used for manufacturing other capacitors or electronic elements.
