The figures show a plan view (A) and a side view (B) of an example of the thickness-shear crystal resonator shape and excitation electrode arrangement of the present invention.The resonator l has 2 vibrating parts, 4 bridge parts 3, and 2 It consists of a frame 4 and two protrusions 5, which are integrally formed by etching. In addition, excitation electrodes 6 and 7 are arranged on the upper and lower surfaces of the vibrating part 2, and by applying an alternating voltage between the two electrodes, thickness shear vibration can be caused. Bridge parts 3 are provided at each of the four corners of the vibrating part 2, and the bridge parts 3 extending in the same direction are connected via a frame 4. Further, the frame 4 has a structure in which a protrusion 5 is provided at the center. Therefore, the energy of the vibrating part 2 is not transmitted to the protruding part 5 at all, so the protruding part 5
Even if the resistor R3 is supported and fixed, good characteristics can be obtained without causing deterioration of the equal series resistor R3.
