PROBLEM TO BE SOLVED: To reduce a dispersion in production of a laminated dielectric filter in which both miniaturization and improvement of performance can be attained. SOLUTION: In three resonant electrodes 16A, 16B and 16C, respective intervals d1 and d2 of adjacent resonant electrodes are not equal, respective short-circuit terminals are connected to a ground electrode 12, at least one principal face of respective electrode faces near the short-circuit terminal is connected through a via hole to the ground electrode 12. In the central resonant electrode 16B and the output side resonant electrode 16C, the area of opened terminal portions 16Ba and 16Ca is set to approximately equalize the frequency fluctuation quantities of the respective resonant electrodes 16A, 16B and 16C caused by the laminate deviation of the three resonant electrodes 16A, 16B and 16C.
