Abstract
A resonator includes a support frame, a rectangular vibrating plate that performs contour vibration in a predetermined direction, and two pairs of support arms. The vibrating plate includes four vibration regions arranged in a row in the lengthwise direction and electrodes disposed in the vibration regions. Each of the vibration regions vibrate with a phase opposite to phases with which the adjacent vibration regions vibrate upon excitation. A center line of a pair of the electrodes in the lengthwise direction is offset from a center line, in the lengthwise direction, of a corresponding vibration region that includes the electrode disposed thereon.
