发明名称 STACKED BANDPASS FILTER
摘要 <p>A capacitance is formed between a ground electrode (109) of a ground electrode formation layer (103) and each of capacitor electrodes (111, 112, 113, 114) of capacitor electrode formation layers (102, 104). An even number of LC parallel resonators is disposed such that via electrodes (131 to 138) and line electrodes (116 to 119) form a plurality of inductor electrodes and, when viewed in a direction in which the inductor electrodes are arranged, the surfaces of the loops of the inductor electrodes overlap each other in part. The loops formed by the inductor electrodes of neighboring LC parallel resonators have opposite directions. The capacitor electrodes (111, 112, 113, 114) have a shape and distribution [arrangement] having point symmetry in plan view.</p>
