摘要： It is an object of the present invention to provide a solid electrolytic capacitor which can reduce impedance, particularly, the ESL and the ESR, and a method for manufacturing such a solid electrolytic capacitor. A cathode electrode 14 is formed on a foil-like aluminum substrate 2 whose surface is roughened. One end portion region of each of foil-like aluminum substrates 3a and 3b is bonded to one of the opposite end portion regions of the foil-like aluminum substrate 2 whose surface is roughened so that electrical connection can be established between the valve metals. One end portion region of each of conductive metal substrates 15a and 15b formed in a lead frame in advance is bonded to one of the other end portion regions of the foil-like aluminum substrates 3a and 3b whose surfaces are roughened, thereby forming anode electrodes. A cathode lead electrode 15c is drawn out from a conductive layer (cathode electrode 14) formed on the foil-like aluminum substrate 2 whose surface is roughened in a direction perpendicular to the major surface of the foil-like aluminum substrate 2.

摘要： Internal dielectric layers isolated between them by a ceramic layer are arranged in a dielectric body, other internal conductor layers also isolated between them by a ceramic layer are arranged in the dielectric body by being isolated from the above internal conductor layers. Each of the all internal conductor layers is formed with a cut part, and a channel part is formed around the cut part, and the channel parts are arranged so that currents flow in mutually reverse directions between channel parts of internal conductor layers adjoining across a ceramic layer. Consequently, the equivalent serial inductance of the multilayer capacitor is largely reduced and fluctuations of a power source voltage of a CPU is made small.

摘要： A dielectric body 12 has internal conductor layers 14 arranged in it. At the far sides of the internal conductor layers 14 separated by ceramic layers 12A, internal conductor layers 16 are arranged. A length W of a side of the dielectric body 12 running along a stacking direction Y of the ceramic layers is made longer than the lengths L and T of any other two sides running along directions (X- and Y-directions) intersecting the side running along the stacking direction (Y-direction). The internal conductor layers 14 and 16 are formed with cut parts 18a and 18b, the internal conductor layers 14 are divided into channel parts 20A and 20B across the cut part 18a, and the internal conductor layers 16 are divided into channel parts 22A and 22B across the cut part 18b. These channel parts are connected through uncut ends 19, whereby the current flows in reverse directions. It is therefore possible to greatly reduce the effective inductance of the multilayer capacitor and reduce the voltage fluctuations of the CPU power source.
