Abstract
A resonator 10 includes a first dielectric substrate 12. An earth electrode 14 is formed almost entirely on one main surface of the first dielectric substrate 12. A first pattern electrode 16 and a first drawing electrode 18 are formed on the other main surface of the first dielectric substrate 12. The first pattern electrode 16 and the first drawing electrode 18 are covered with an insulation layer 20. A second pattern electrode 22 and a second drawing electrode 24 are formed on the insulation layer 20. The second pattern electrode 22 and the second drawing electrode 24 are covered with a protecting layer 26. The earth electrode 14 is covered with a protecting layer 28. The earth electrode 14, the first pattern electrode 16 and the second pattern electrode 22 are connected with each other through a terminal electrode 30a. Terminal electrodes 30b and 30c are connected to the earth electrode 14. A drawing terminal electrode 32 is connected to the first drawing electrode 18 and the second drawing electrode 24.
