PURPOSE:To prevent the dispersion of electric characteristics and to improve the yield of products as well by forming a counter electrode faced to the resonance electrode of a first dielectric substrate on a first dielectric substrate and electrically connecting these both electrodes. CONSTITUTION:On one main face 3a of a second dielectric substrate 3, counter electrodes 8 and 8 composed of the same pattern as a resonance electrode 4 are formed. The counter electrode 8 is formed on the second dielectric substrate 3 and since the said counter electrode 8 is faced to the resonance electrode 4 of a first dielectric substrate 2 and electrically and mechanically connected to it by a conductive adhesive agent 9, the dispersion of a contact degree in the conventional case of forming the resonance electrode only on one face can be prevented and therefore, the fluctuation of an effective dielectric constant can be avoided. As the result, the dispersion of electric characteristics such as a central frequency and band width or the like can be prevented. |
