PROBLEM TO BE SOLVED: To suppress a path length deviation of each inductor element and to equalize an attenuation characteristic. SOLUTION: A laminated dielectric filter has a laminated body where a plurality of inductor patterns P5-P8 composing an inductor element are formed between dielectric layers by laminating a plurality of dielectric layers 25 (100b) and one end portion of the inductor element is exposed to one side, and terminal electrodes 17-20 formed on a side of the laminated body in a direction of lamination at regular intervals like a belt. The inductor patterns P5-P8 are arranged at regular intervals to be formed, deviation amounts 9-12 between inductor pattern center lines 1-4 and terminal electrode central lines 5-8 are more in the inductor patterns P5-P8 farther from a dielectric layer central line 28, and the inductor patterns P5-P8 are line-symmetric with the dielectric layer central line 28 as a line of symmetry in the laminated dielectric filter. Since it becomes possible to suppress a deviation of a path length of each inductor element, it becomes possible to suppress a deviation of an attenuation characteristic of each inductor element.
