PIEZOELECTRIC VIBRATOR AND METHOD FOR MANUFACTURING PIEZOELECTRIC VIBRATOR
Document Type and Number:
WIPO Patent Application WO/2022/130670
Kind Code:
A1
Abstract:
A quartz vibrator 1 comprises: a quartz vibration element 10 having a quartz piece 11, excitation electrodes 14a, 14b, and connection electrodes 16a, 16b; a substrate 30; and a conductive holding member 50 provided between the connection electrodes 16a, 16b of the quartz vibration element 10 and the substrate 30 so as to hold the quartz vibration element 10 on the substrate 30. A through-hole 120 is provided to a region of the quartz piece 11 between the excitation electrode 14 and a peripheral edge 110 of the quartz piece 11 in the longitudinal direction. The conductive holding member 50 is provided to straddle the peripheral edge 110 of the quartz piece 11 along the longitudinal direction, and has fillets 55 respectively formed on a first side surface 111 of the peripheral edge 110 and a first wall surface 121 of the through-hole 120.
