PROBLEM TO BE SOLVED: To solve the problem that it is difficult to attain miniaturization and high performance of a laminated dielectric filter. SOLUTION: A laminated dielectric filter has at least strip line resonators L1, L2 in first and second stages, an interresonator connection capacity conductor layer 33, and an input/output conductor layer 28. The resonators L1, L2 are each provided with an inductor 2 consisting of a plurality of dielectric layers, at least first, second, third and fourth strip line conductor layers 13, 14, 16 and 17, and ground conductor layers 22, 25. The first and third layers 13, 16 are arranged so as to face each other through the dielectric layers. The second and fourth layers 14, 17 are arranged so as to face each other through the dielectric layers. The layer 28 is arranged in the dielectric layers different from those in which the layer 33 is arranged. COPYRIGHT: (C)2004,JPO
