Abstract
The invention includes the steps of preparing a mixed solution containing a polymerizable monomer, an oxidant, and a solvent; immersing a capacitor element in the mixed solution; and heating the capacitor element immediately over the boiling point of the solvent, after taking out the capacitor element from the mixed solution, in order to evaporate the solvent and form a conductive polymer layer on the capacitor element; the heating is carried out at a rate capable of generating a force able to tear open the conductive polymer. This method provides a capacitor having a high capacitance attainment ratio, an excellent dissipation factor, and a superior impedance characteristic.
