ABSTRACT:
An LC resonating component, such as multilayered LC filter 1, is provided having a high Q-value and a low profile. The filter 1 comprises an insulating sheet 2 having a ground electrode 3 on its surface and in its center a via hole 7 connected to the ground electrode 3, an insulating sheet 2 having a via hole 4 in its center, insulating sheets 2, 2 having capacitor electrodes 5, 6 on their respective surfaces, and a protective insulating sheet 2. The via hole 7 is connected to the via hole 4, wherein the via holes 4 and 7 together comprise an inductor conductive body 8. The inductor conductive body 8 is perpendicular to the planes defined by capacitor electrodes 5, 6, and thus the magnetic flux created around the inductor conductive body 8 does not penetrate the capacitor electrodes 5, 6.
