Claims

[Scope of utility model registration request]

Excitation electrodes for contour vibration are arranged on both sides of a vibrating part machined into a quadrilateral shape, and two electrodes drawn out from the ends of both sides of the vibrating part are placed on a line that passes through the center of gravity of the vibrating part and bisects the vibrating part. In a contoured quartz crystal resonator in which a drawer, a support part that commonly fixes two legs extending parallel to the longitudinal direction of the vibrating part, and the vibrating part are integrally formed, near the side surface of the support part. A contoured crystal resonator characterized in that two lower end grooves are provided from the bottom in parallel with the side surface of the support part.
