<p>A piezoelectric vibrator element (10, 60, 70, 71) includes a vibrating portion (22) that excites thickness-shear vibration, and a peripheral portion (17, 62) that is disposed on the periphery of the vibrating portion (22). A buffering portion (14) and a mount portion (12) are sequentially connected to the peripheral portion (17, 62). The buffering portion (14) includes a slit (16) formed between the mount portion (12) and the peripheral portion (17, 62). The mount portion (12) has notches (12a) which are formed at both end portions in a direction orthogonal to an arrangement direction of the mount portion (12), the buffering portion (14), and the peripheral portion (17, 62).</p> |
