LAMINATED DIELECTRIC FILTER

摘要

PROBLEM TO BE SOLVED: To increase the yield of a laminated dielectric filter by suppressing the deterioration of a characteristic which is caused by the cutting of a dielectric substrate. SOLUTION: Grounding electrodes are formed on at least the both main surfaces of the dielectric substrate 14 which is constituted by laminating a plurality of dielectric layers and, then, the laminated dielectric filter 10A is provided with two resonance electrodes 16A and 16B and internal layer grounding electrodes (30A and 32A) and (30B and 32B) which are formed to face the opening end parts 16Aa and 16Bb of the resonance electrodes 16A and 16B in the dielectric substrate 14. In the filter 10A, the width Wb of the short end parts 16Ab and 16Bb of the resonance electrodes 16A and 16B is set to be wider than the width Wc of the middle parts 16Ac and 16Bc (Wb>Wc).
