Abstract
A tuning fork type vibrator element, as a vibrator element, includes a base formed on a plane including a first axis and a second axis orthogonal to the first axis, a connection portion extending in a first axis direction from the base, with a thickness thereof being smaller than that of the base and a vibrating arm extending in the first axis direction from one end portion of the connection portion, with a thickness thereof being the same as that of the connection portion, in which the vibrating arm performs flexural vibration along a vertical direction with respect to the plane, and in which the connection portion is provided such that a relationship between a length L2 in the first axis direction of the connection portion and a length L1 in the first axis direction of the vibrating arm falls within a range of L1/15≦L2≦L1.
