Resonator element, resonator, oscillator, and electronic apparatus

摘要

A resonator element includes a base section, a pair of vibrating arms projecting from the base section in a +Y-axis direction, and arranged in an X-axis direction intersecting with the Y-axis direction with a distance in a plan view, and a support arm disposed between the pair of vibrating arms and projecting from the base section in the +Y-axis direction. The base section includes a first shrunk-width portion disposed on an opposite side to the side on which the support arm projects taking the center of the base section as a boundary, and within a range of the distance, and having a length in the X-axis direction gradually decreasing with a distance from the support arm in a plan view.

1. A resonator element comprising:
a base section; a pair of vibrating arms projecting from the base section on a same side, and arranged with a distance in a direction intersecting with a direction of the projection in a plan view; and a support arm disposed between the pair of vibrating arms, and projecting from the base section on the same side as the pair of vibrating arms, wherein the base section includes a first shrunk-width portion disposed on an opposite side to the side on which the support arm projects taking a center of the base section as a boundary, and having a width in the intersecting direction gradually decreasing with a distance from the support arm in a plan view, and wherein a maximum value of a width of the first shrunk-width portion in the intersecting direction is larger than an amount of the distance.
