<p>A stacked type dielectric filter (10A) comprises two sets of resonators (14A, 14B) arranged in a dielectric substrate (12) constructed by laminating a plurality of dielectric layers, in which each of the resonators (14A, 14B) includes two resonance electrodes (16A, 16B) superimposed in a stacking direction; wherein one resonance electrode (16A) of the two resonance electrodes (16A, 16B) for constructing each of the resonators (14A, 14B) is formed to have a wide width as compared with the other resonance electrode (16B). Accordingly, even when any stacking deviation occurs in the plurality of resonance electrodes during the production, it is possible to decrease the variation of characteristics. Thus, it is possible to maximally exhibit the effect (high Q value, small size, and high performance) to be obtained by constructing the resonator by superimposing the plurality of resonance electrodes in the stacking direction. <IMAGE></p> |
