Title:
PIEZOELECTRIC VIBRATOR
Document Type and Number:
WIPO Patent Application WO/2018/043340
Kind Code:
A1
Abstract:
A piezoelectric vibrator (1) is provided with: a piezoelectric vibration element (100); a substrate (300) having a first main surface and a second main surface on the reverse side of the first main surface; and conductive holding members (340, 342) that hold the piezoelectric vibration element on the first main surface of the substrate. Each of the conductive holding members contains a plurality of metal particles (420), and a plurality of spherical spacers (410) that hold the piezoelectric vibration element by having a predetermined gap from the first main surface of the substrate, said conductive holding members having relationship of Wave<{(2/√3)-1}×Vave, where the average particle diameter of the spherical spacers is represented by Vave, and the average particle diameter of the metal particles is represented by Wave.
