ABSTRACT:
A contour vibration mode piezoelectric resonator has a vibrating portion and at least one supporting portion integrally connected to the vibrating portion by way of a bridge portion. The supporting portion comprises a resilient portion directly connected to the vibrating portion, an attenuation portion integrally connected to the resilient portion and which is insubstantially displaced by vibration during use and a fixing portion fixable on a supporting member and which is either integrally connected to or forms a part of the attenuation portion.
