Patent ID: 8212633

Claim:
A laminated band pass filter comprising: a laminated body including a plurality of dielectric layers and a plurality of electrode layers laminated together; a plurality of LC parallel resonators including a ground electrode and capacitor electrodes arranged on the plurality of electrode layers and inductor electrodes connected to the ground electrode and to the capacitor electrodes; wherein the inductor electrodes include line electrodes and via electrodes; first ends of the line electrodes are connected to the capacitor electrodes by the via electrodes, and the via electrodes are not shared by any of the inductor electrodes and second ends of the line electrodes are connected to the ground electrode by the via electrodes; connection points between corresponding ones of the via electrodes and the capacitor electrodes define a starting point of the inductor electrodes and connection points between corresponding ones of the via electrodes and the ground electrode define the ending points of the inductor electrodes; each of the inductor electrodes are arranged in a loop shape when viewed from a perpendicular or substantially perpendicular direction relative to a lamination direction of the laminated body; the line electrodes of the inductor electrodes of at least two of the plurality of LC parallel resonators are arranged on different electrode layers of the plurality of electrode layers; the at least two of the plurality of LC parallel resonators including the inductor electrodes arranged on the different electrode layers are arranged in an arrangement direction that is perpendicular or substantially perpendicular to the lamination direction of the plurality of dielectric layers and the plurality of electrode layers, and the inductor electrodes of the at least two of the plurality of LC parallel resonators are arranged such that the loops overlap with each other when viewed from the arrangement direction.
