Laminated bandpass filter, high-frequency component and communications apparatus comprising them

A three-stage-resonator, laminated bandpass filter comprising first to third resonator electrodes arranged such that adjacent electrodes are electromagnetically coupled, an input terminal connected to one of the resonator electrodes on both sides, and an output terminal connected to the other of the resonator electrodes on both sides, each of the adjacent first and second resonator electrodes having one-side end connected to a grounded capacitor and the other-side end directly grounded, the third resonator electrode having said one-side end directly grounded and said other-side end connected to a grounded capacitor, coupling capacitors being formed between said resonator electrodes, electrodes for both of said resonator electrodes and said coupling capacitors being formed in said laminate, and said coupling-capacitor electrodes overlapping two or more of said resonator electrodes via no ground electrode when viewed in a lamination direction.
