摘要： In a piezoelectric vibrator capable of vibrating under an expansion mode of vibration, which has a piezoelectric vibrating element including a generally rectangular vibrateable substrate, made of a metallic material having a constant modulus of elasticity. The substrate is supported by a retaining member through a pair of connecting elements which extend outwardly from an arbitrarily chosen pair of side edges, respectively, so as to terminate in rigid connection with the retaining member. The width of each of the connecting elements as measured in a direction lengthwise of each of said edges is selected to be within the range of 1/7 to 1/3 of the length of said each side edge.

摘要： A piezoelectric vibrator comprises a substrate consisting of Elinvar, in which a vibrating element is formed as an island. The vibrating element is connected to and supported by strip-like connecting portions which are connected with the surrounding frame. A piezoelectric film is formed on the surface of the vibrating element. Of the longitudinal end portions of the vibrating element in the vicinity of the connecting portions, one main surface side is formed as a thin-plate portion by etching, while the rest of the vibrating element has its thickness intact. The longitudinal edges of vibrating element are defined by etching carried out simultaneously with or after the previous etching step.
