PURPOSE: Method for forming an electrolytic layer of a solid electrolytic condenser is provided to lower the value of Equivalent Series Resistance by reducing the number of porosity formed in a conductive high polymer. CONSTITUTION: In the method for forming an electrolytic layer of a solid electrolytic condenser, an oxidation film(14) is formed on a surface of valve metal such as tantalum or aluminum and the electrolytic layer is formed there above. A high polymer layer(16) is formed on the surface of the oxidation film(14) by using an electrolytic polymerization of a monomer such as pyrrole, thiophene, furan, aliline, acethylene, etc. The porosities(18) in the high polymer layer(16) are impregnated with the hetero cyclic compound such as polypyrrole, polythiophene polyfuran which are melted by a solvent such as NMP, chlorotorn, aceton, methanol, DMSO. After impregnation of the hetero cyclic compound, the porosities(18) are removed by the volatilization of the solvent.
