A solid electrolytic capacitor includes an anode formed of a valve metal and having a roughened surface layer at a surface thereof, a dielectric layer formed of a valve metal oxide and formed on the anode, a cathode formed of a conductive polymer layer formed on the dielectric layer, an anode lead formed adjacent to and integrally with the anode, and a resist formed of an insulating material and delimiting the anode and the anode lead. The anode and the anode lead have a first stepped portion having both surfaces each cut in a thickness direction and covered with the resist, and the anode lead has a second stepped portion having both surfaces each cut deeper in the thickness direction than the first stepped portion.

In a solid electrolytic capacitor including a porous valve-acting metal, an anode conductor has a large number of pores having openings on the surface thereof according to the porosity of the valve-acting metal. A solid electrolyte layer is formed on the surface of the anode conductor so as to be filled in at least a portion of each of the pores and to close the openings thereof. Further, a cathode conductor is formed on the solid electrolyte layer. Preferably, the solid electrolyte layer has a two-layer structure with two layers having different particle sizes.

The present invention provides a method for easily removing metal impurities from an indole derivative trimer containing the metal impurities, which method involves mixing the indole derivative trimer containing the metal impurities with an imidazole compound in a solvent comprising water under heating, and filtering and separating the indole derivative trimer, from which the metal impurities have been removed, from the obtained mixture. Further, mixing a protonic acid allows the doping of the indole derivative trimer to be conducted simultaneously with the metal impurity removal, whereby the indole derivative trimer can be used as an electrode active substance of an electrochemical cell.
