Abstract:
A small low-loss laminated band pass filter attains steep attenuation from a pass band to out-of pass band and reduced ripple in the band. Capacitances are generated between a ground electrode on a ground electrode forming layer and capacitor electrodes on a capacitor electrode forming layer, a plurality of inductor electrodes are defined by via electrodes and the line electrodes, and portions of respective loop surfaces of the inductor electrodes overlap with one another when viewed from a direction of arrangement of the inductor electrodes. Furthermore, a line electrode is arranged on a first line electrode forming layer and line electrodes are arranged on a second line electrode forming layer.
