Abstract

PURPOSE:To obtain a longitudinal crystal resonator with small resonance leakage by providing an R-corner to a bridge connecting a vibration part and a bending part. CONSTITUTION:The resonator 1 consists of the resonator part 2 and the support part 3 and they are formed incorporatedly by the etching method. The shape between the resonator part 2 and the support part 3, that is, the shape of the bridge part is formed nearly the same in four faces by providing the R-corner in a way that the support 3 provided to both sides of the vibration part 2. Since the R-corner is provided to the bridge part of the support in this way, symmetry is obtained and the vibration leakage is reduced in forming the vibrator by etching.
