Document Type and Number:
WIPO Patent Application WO/2018/092572
Kind Code:
A1
Abstract:
[Problem] To curb fluctuations in properties caused by changes in the external environment, thereby improving reliability, in a quartz oscillation device comprising a quartz oscillator having a sandwich structure. [Solution] This quartz oscillator 100 is obtained by hermetically sealing a quartz oscillator 101 and an IC chip 102 within a package 103. The quartz oscillator 101 comprises: a quartz oscillator plate 2 having a first excitation electrode 221 formed on one principal surface thereof, and a second excitation electrode 222 forming a pair with the first excitation electrode 221 of the other principal surface; a first sealing member 3 that covers the first excitation electrode 221 of the quartz oscillator plate 2; and a second sealing member 4 that covers the second excitation electrode 222 of the quartz oscillator plate 2. The first sealing member 3 and the quartz oscillator plate 2 are bonded to one another, and the second sealing member 4 and the quartz oscillator plate 2 are bonded to one another, forming a structure in which the oscillating part 22 of the quartz oscillator plate 2 which includes the first excitation electrode 221 and the second excitation electrode 222 is hermetically sealed.
