Abstract
A resonator is provided that includes a vibration member that includes a substrate, a metal layer formed along one of main surfaces of the substrate, and a piezoelectric thin film disposed between the substrate and the metal layer. The vibration member vibrates such that a main vibration is a contour vibration. Moreover, a frame surrounds at least a portion of the vibration member, and a support unit connects the vibration member to the frame. The vibration member includes depressed portions on or above the one of main surfaces where the piezoelectric thin film is removed.
