| titleOfInvention | Piezoelectric vibration device |
| abstract | (57) [Summary] [PROBLEMS] To provide a piezoelectric vibration device that suppresses spurious vibration modes generated in the vicinity of the main vibration, makes the passband characteristics excellent and wide, and improves the guaranteed attenuation characteristics outside the passband. provide. A weight reducing unit or a weight adding unit is provided in at least a part near the outer periphery of an input electrode and an output electrode or a common electrode, and in a part where a nonharmonic overtone mode is excited relatively strongly. Further, the area of the common electrode is increased with respect to the total area of the input electrode and the output electrode, and the weight reducing unit or the weight adding unit is set to a range extending to the common electrode portion facing the input electrode and the output electrode. Further, the electrodes formed on any of the main surfaces of the quartz plate are made thick. Here, the thickness of the common electrode formed on one main surface of the quartz plate is twice as large as the thickness of the input electrode and the output electrode formed on the other main surface. Preferably, the thickness is 10 times. Silver, silver alloy, gold, and gold alloy are used as these electrode materials. |
