PROBLEM TO BE SOLVED: To provide a method for manufacturing a solid electolytic capacitor capable of stabilizing an electric properties by solving the problem that the capacitance of the capacitor cannot be brought out satisfactorily nor an ESR cannot be decreased due to unsatisfactory filling of a polymerisation solution comprising monomer and oxidant. SOLUTION: The method comprises the steps of putting a polymerisation solution 1 comprising monomer and oxidant in an impregnating bath 3, closing an opening-closing valve 4 after putting in a capacitor element 2, dipping the capacitor element 2 with an inside of the impregnating bath 3 decompressed, and opening the valve 4 to release the inside of the bath 3 at atmosphere pressure. The method further comprises the steps of closing the valve 4 again to decompress the inside of the bath 3, and opening the valve 4 to release the inside on the bath 3 at atmosphere pressure. This substantially impregnates the inside of the element 2 with the solution 1 to improve the electric properties. COPYRIGHT: (C)2004,JPO&NCIPI
