摘要

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.

1. A vibrator element comprising:
a base that includes a plane that includes a first axis and a second axis orthogonal to the first axis; a connection portion that is smaller in thickness than the base and extends along the first axis from the base; and a vibrating arm that extends along the first axis from one end portion of the connection portion, wherein the vibrating arm performs flexural vibration in a direction that intersects with respect to the plane, and wherein a length L2 of the connection portion in a first axis direction and a length L1 of the vibrating arm in the first axis direction fall within a range of L1/15≦L2≦L1.
