PIEZOELECTRIC VIBRATOR, PIEZOELECTRIC VIBRATION COMPONENT AND MANUFACTURING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a piezoelectric vibrator that can be stably supported by minimizing the attenuation of vibration energy. SOLUTION: A piezoelectric substrate 1 includes a vibrating part 101 and a non-vibrating part 102. Grooves 2 are provided around the vibrating part 101 in at least one of two principal planes 100 and 130 existing in the thickness direction of the piezoelectric substrate 1 and separate the vibrating part 101 from the non-vibrating part 102.
