Abstract
A resonator is provided that suppresses a shift in resonant frequency. The resonator includes a vibration member including vibration arms extending therefrom with two or more of the vibration arms performing out-of-plane bend with different phases. Moreover, the resonator includes a base having a front end connected to the vibration arms and a rear end opposing the front end and structured to bend in a direction of the out-of-plane bend when the vibration arms perform the out-of-plane bend. Moreover, a frame surrounds a periphery of the vibration member and one or more holding arms are positioned between the vibration member and the frame. One end of each holding arm is connected to the base and the other end of the holding arm is connected to the frame. The holding arms bend in the direction of the out-of-plane bend when the base bends.
