保持器の構造。 A piezoelectric vibrating device that utilizes waves excited in the surface or bulk of the piezoelectric substrate by an interdigital transducer electrode formed on one surface of the piezoelectric substrate. On the substrate support surface, a land of a minute area is provided at a position where a portion of the support surface that corresponds to approximately the center of the electrode that determines the resonant frequency of the piezoelectric vibration device comes into contact, and a groove that allows adhesive to flow around the land. A structure of a piezoelectric device holder characterized by providing.
