  • Piezoelectric vibrator element, piezoelectric module, and electronic device
    Patent number: 8963402
    Abstract: A piezoelectric vibrator element includes a vibrating portion that excites thickness-shear vibration, and a peripheral portion that is disposed on the periphery of the vibrating portion and has a thickness thinner than the vibrating portion, the vibrating portion and the peripheral portion being formed in a piezoelectric substrate. A buffering portion and a mount portion are sequentially connected to the peripheral portion. The buffering portion includes a slit formed between the mount portion and the peripheral portion. The mount portion has notches which are formed at both end portions in a direction orthogonal to an arrangement direction of the mount portion, the buffering portion, and the peripheral portion.
