Abstract
A piezoelectric resonator with a rectangular parallelepiped resonator. A lithium niobate single crystal is used as the resonator chip material. Each of the opposed main surfaces of the resonator chip is arranged to be a surface of a rotated Y-cut plate which is rotated 165.+-.5 degrees about an X-axis. The angle of the longitudinal direction of the resonator chip is arranged to be 90.+-.5 degrees with respect to the X-axis of the rotated Y-cut plate.
