Abstract
A multilayer LC filter includes a multilayer body in which insulator layers, a ground electrode, capacitor electrodes, a planar electrode, and via electrodes includes open-side via electrodes connecting the capacitor electrodes and the planar electrode and short-circuit side via electrodes connecting the planar electrode and the ground electrode, an inductor is provided by a conductive path extending from the capacitor electrodes to the ground electrode through the open-side via electrodes, the planar electrode, and the short-circuit side via electrodes, a capacitor is provided by capacitance generated between the ground electrode and the capacitor electrodes, the inductor and the capacitor are connected in parallel to define LC resonators, and it is assumed that the short-circuit side via electrodes of all of the LC resonators in the multilayer body are made common.
