Abstract

PURPOSE:To improve the sensitivity to a stress and the CI value by selecting a cross sectional area of a connecting member provided between a holding part of a piezoelectric vibrator and a vibrator part smaller than that of the holding member and larger than that of the vibrator member. CONSTITUTION:The titled vibrator is a twin tuning fork piezoelectric vibrator used especially for a pressure sensor, connection parts 4, 4 are provided between vibrator parts 1, 1 and holding parts 3, 3 and the cross sectional area of the connection members 4, 4 is selected smaller than that of the holding members 3, 3 and larger han that of the vibrator members 1, 1. Thus, the free vibration of the vibrator is not hindered by the fixing by the holding parts, the Q is maintained and the sensitivity a stress is excellent and the leakage of vibration is reduced.
