ABSTRACT:
A piezoelectric component includes an input terminal plate, a series ceramic resonator, an output terminal plate, a parallel ceramic resonator and a ground terminal plate stacked between a first case and a second case. Lead portions of the input terminal plate, the output terminal plate and the ground terminal plate are outwardly projected from the cases. These terminal plates and the ceramic resonators are in pressure contact with each other to attain electrical conduction therebetween and thus, form a single-section ladder type filter.
