Abstract:
A band pass filter comprising:a laminated body including a plurality of insulation layers, a plurality of inductor patterns, and a plurality of capacitor patterns, a plurality of inductors provided inside of the laminated body and including the inductor patterns; and a plurality of capacitors provided inside of the laminated body by the capacitor patterns and arranged opposite to the inductor patterns so that a plurality of LC resonators are defined; wherein the capacitor pattern of a first LC resonator of at least one pair of adjacent LC resonators and the inductor pattern of a second LC resonator of the at least one pair of the LC resonators are disposed on a surface of a first Insulation layer, the inductor pattern of the first LC resonator of the at least one pair of the LC resonators and the capacitor pattern of the second LC resonator thereof are disposed on a surface of a second insulation layer, and the capacitor pattern and the inductor pattern disposed on each of the first and second insulation layers extend to the same side of respective ones of the first and second insulation layers so as to be exposed; and a length of the capacitor pattern of the first LC resonator is different from a length of the inductor of the second LC resonator disposed on the surface of the first insulation layer, and a length of the capacitor pattern of the second LC resonator is different from a length of inductor pattern of the first LC resonator disposed on the second insulation layer.
