摘要：
A vibrator device includes a base, a relay substrate that is supported by the base, and a vibrator element that is supported by the relay substrate. In addition, the vibrator element includes a vibration substrate formed of a piezoelectric single-crystalline body and an excitation electrode disposed on the vibration substrate. In addition, the relay substrate includes a substrate formed of the piezoelectric single-crystalline body. A crystal axis of the substrate and a crystal axis of the vibration substrate are shifted from each other.
