Abstract: The capacitor element includes as an anode an aluminum foil in the form of a thin plate, an oxide layer formed as a dielectric on the surface of the anode, and a conductive polymer layer formed as a cathode on the dielectric. The capacitor is formed by drawing terminals in arrays from the capacitor element. On the upper side of the capacitor element is provided an embossed copper foil 11 for suppressing deformation of the capacitor element. The anode terminals and the cathode terminals are drawn to the lower side of the capacitor element. The anode terminals and the cathode terminals are alternately formed at the same pitch in the x-direction and the y-direction, so that the heteropolar terminals are disposed at the adjacent positions with respect to any one of the terminals.

The polymeric product layer is doped with an organic sulfonic acid selected from the group consisting of an aromatic polysulfonic acid, an organic sulfonic acid having a hydroxy group, an organic sulfonic acid having a carboxyl group, an alicyclic sulfonic acid, and a benzoquinone sulfonic acid.

Abstract: A fabrication method of a solid electrolytic capacitor is provided, which decreases the necessary repetition number of adhesion steps of an oxidizing agent and a monomer of a conducting polymer to a dielectric of the capacitor while keeping the coverage ratio at a satisfactorily high level. A capacitor body with an oxide layer is first immersed into an oxidizer solution at a room temperature under an atmospheric pressure. The oxidizer solution has a viscosity ranging from 100 to 500 cp at room temperature under the atmospheric pressure. Then, the oxidizer solution adhered to the oxide layer is dried to remove a solvent of the adhered solution and to leave the oxidizing agent on the oxide layer. The oxidizing agent left on the oxide layer is in solid phase at room temperature under the atmospheric pressure. The capacitor body with the oxide layer is immersed into a monomer of a conducting polymer.

Abstract: A fabrication method of a solid electrolytic capacitor is provided, which is able to form the surface irregularity of a conductive polymer layer serving as a solid electrolyte with good controllability and good stability. A capacitor body is formed by a valve metal. The body serves as an anode of the capacity. An oxide layer is formed to cover the surface of the capacitor body. The oxide layer serves as a dielectric of the capacitor. A first conductive polymer layer is formed on the oxide layer. The first conductive polymer layer serves as a part of a solid electrolyte of the capacitor. A powder of a conductive polymer is deposited on the first conductive polymer layer by spraying a fluid containing the powder on the first conductive polymer. A second conductive polymer layer is formed on the first conductive polymer layer to cover the deposited powder. The surface of the second conductive polymer layer has irregularities corresponding to the deposited powder.
