摘要: The present invention is able to reduce a CI value without requiring precise processing of a crystal blank.
An electrode structure of a crystal unit (1) according to the present invention includes driven electrodes (21, 22) arranged at least at a center on main surfaces (11, 12) of a crystal blank (10). The driven electrodes (21, 22) have a structure in which vibration energy of thickness shear vibration of the crystal blank (10) is concentrated in a central region of the crystal blank (10).
