<p><P>PROBLEM TO BE SOLVED: To reduce secular changes in a piezoelectric device. <P>SOLUTION: A piezoelectric device 100 includes: a flat-shaped piezoelectric vibration element 30; and a plurality of support members 20 each having holding portions 20a for supporting side surfaces of the piezoelectric vibration element 30 through brazing fillers 40 and that sandwich and support the piezoelectric vibration element 30. The brazing fillers 40 are formed so as to become narrower, in a planar view, from the piezoelectric vibration element 30 toward the respective holding portions 20a of the support members 20. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
