Patent ID: 8896185

Claim:
A piezoelectric device, comprising: a piezoelectric frame, including a piezoelectric vibrating piece, a frame body surrounding the piezoelectric vibrating piece and separated therefrom by at least one through hole, and a supporting portion for supporting the piezoelectric vibrating piece to the frame body, each piezoelectric frame having a first surface and a second surface; a package lid having a first connecting surface, in which at least a part of the first connecting surface opposes to the first surface of the frame body; a package base, including a mounting surface for forming a pair of external electrodes and a top surface formed opposite the mounting surface, said top surface including at least a part of a second connecting surface opposed to the second surface; a first sealing material formed between the first connecting surface and the first surface of the frame body; and a second sealing material formed between the second connecting surface and the second surface of the frame body; wherein at least one of the first sealing material or the second sealing material extends onto the side surface of the opening through-hole of the frame body.
