<p>A piezoelectric device (100) comprises: a piezoelectric vibrating piece (101); a frame body (105) separated from piezoelectric vibrating piece by through-hole (108); a piezoelectric frame (10) having a supporting portion (104), a first surface (Me) and a second surface (Mi); a package lid (11) having a first connecting surface (M1) a package base (12), including a mounting surface (M4) for forming a pair of external electrodes (125) and a top surface having a second connecting surface (M2); a first sealing material (LG1) formed between the first connecting surface and the first surface; and a second sealing material (LG2) formed between the second connecting surface and the second surface. The first sealing material or the second sealing material extends to a side surface (M3) of the through-hole.</p> |
