Abstract
A multi-layered LC composite component achieves greatly increased attenuation in the proximity of a central frequency without increasing insertion loss. In the arrangement of the multi-layered LC composite component, an end of each of inductor patterns is connected to a connecting pattern to be short-circuited. These inductor patterns define inductors. Frequency-adjusting capacitor patterns are opposed to open-circuited ends of the inductor patterns to define capacitors. As a result, the capacitors and the inductors define LC resonators. The connecting pattern is opposed to shield patterns via insulating sheets to define a common capacitor.
