Abstract

PURPOSE:To obtain a longitudinal crystal resonator with less resonance leakage by improving the shape and size of the support. CONSTITUTION:The resonator 1 is constituted by a resonator part 2 and a support part 3 and formed incorporatedly by the etching method. The support part 3 provided to both sides of the resonator part 2 is formed symmetrically and the bent part 4 connected to the resonator part 2 is connected to a mount part 7 and projected in opposite direction with the mount part 7. Thus, the displacement in the broadwise direction of the resonator part 2 is converted into the bending mode of the support part 3 to prevent the degree of freedom of the resonance from being suppressed. Thus, the longitudinal crystal resonator without any resonance leakage is obtained even when it is fixed at the mount part 7.
