Abstract:
A vibrator element includes a pair of first and second drive vibrating arms that extend in opposite directions from a base portion; a first weight that is spaced from a tip of at least one of the first and second drive vibrating arms toward the base portion and is provided in a first region of the at least one of the drive vibrating arms; and a second weight that is provided in a second region that is a region between a tip of the first weight and the tip of the at least one of the drive vibrating arms. When an area of the first region is represented as A1, a mass of the first weight is represented as B1, an area of the second region is represented as A2, and a mass of the second weight is represented as B2, B1/A1>B2/A2 is established.
