Multilayered LC filter
A multi-layered LC filter includes a plurality of insulating sheets stacked on each other and inductor via holes that are connected to each other in a stacking direction of insulating sheets, forming two columnar inductors. First ends of the inductors are connected to external ground electrodes via internal ground patterns, respectively. The external ground electrodes are electrically connected via a bridge pattern disposed in proximity to the inductors, allowing adjustment of the value of the magnetic coupling between LC resonators without changing the size of the filter.
