Document Type and Number:
WIPO Patent Application WO/2020/195818
Kind Code:
A1
Abstract:
The present invention comprises: a crystal vibration element 10 that includes a crystal piece 11 having a center section 11a and a peripheral section 11b, a pair of excitation electrodes 14 provided on the center section 11a, and a pair of connection electrodes 16 provided on the peripheral section 11b; a substrate 30 that supports the crystal vibration element 10 by linking with the connection electrodes 16 at one thickness-direction side with an electrically conductive holding member 36 interposed therebetween; and a lid section 20 that covers the vibration element at the other thickness-direction side. The crystal piece 11 has at least one projection section 11c provided in contact with the center section 11a, and, when the crystal vibration element 10 tilts toward the substrate 30 or the lid section 20 using the side at which the pair of connection electrodes 16 is provided as a fulcrum, the at least one projection section 11c is provided projecting in the thickness direction at a position for which the at least one projection section 11c contacts the substrate 30 or the lid section 20.
