Abstract
Disclosed herein is an energy trap type piezo-resonator (11) utilizing a thickness shear vibration mode, which is prepared by forming electrodes (13, 14) on both major surfaces of a piezoelectric substrate (12) and providing dynamic damper parts (17, 18) being held between grooves (15a, 15b; 16a, 16b) for preventing leakage of vibration from a vibrating part opposing the electrodes (13, 14) to each other to end portions of the piezoelectric substrate.
