Abstract
A resonator that includes a piezoelectric vibrator, a frame, and a first node generator between the piezoelectric vibrator and the frame. Moreover, a first connecting arm connects the first node generator to the piezoelectric vibrator that opposes the first, and a first holding arm connects the first node generator to a part of the frame that opposes the first node generator. The first node generator includes a width extending in a second direction, which is orthogonal to a first direction of the first connecting arm, that is a maximum width where the first node generator is closer to the first connecting arm than a center of the first node generator relative to the first direction. Moreover, the width of the first node generator gradually decreases from the maximum width as the first node generator extends towards the first holding arm.
