ABSTRACT:
A dielectric body12has internal conductor layers14arranged in it. At the far sides of the internal conductor layers14separated by ceramic layers12A, internal conductor layers16are arranged. A length W of a side of the dielectric body12running 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 layers14and16are formed with cut parts18aand18b, the internal conductor layers14are divided into channel parts20A and20B across the cut part18a, and the internal conductor layers16are divided into channel parts22A and22B across the cut part18b. These channel parts are connected through uncut ends19, 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.
