Abstract:
A resonator element is provided. A base portion includes a first base portion, a second base portion, and a connecting portion. The base portion includes a width-decreasing portion that is provided at an end of the connecting portion on the first base portion side and that has a width along an X-axis direction which continuously decreases toward the second base portion. An outer edge of the width-decreasing portion and an outer edge of the connecting portion form a continuous line that does not include a corner portion, when seen in a plan view. When an angle between a tangent of a portion of the curved line on the first base portion side and a segment parallel to the X-axis direction is set to θ, a relation of 0°
