CRYSTAL DEVICE AND METHOD FOR MANUFACTURING CRYSTAL DEVICE

摘要

[PROBLEMS] To provide a crystal device where a lid and a base are formed entirely of crystal and bonded by siloxane bond (Si-O-Si). [MEANS FOR SOLVING PROBLEMS] A crystal device (100) comprises a crystal frame (50), which is made of crystal and has a crystal oscillation piece with an electrode pattern and an outer frame (51) for supporting the crystal oscillation piece; and a crystal base (40), which is made of crystal and has a connection electrode formed on the first surface and an external electrode formed on the second surface on the side opposite to the first surface and is conductive to the connection electrode. The connection electrode (42) is brought into contact with the electrode pattern (33) and the outer frame (51) is not brought into contact with the crystal base (40) when the crystal frame and the crystal base are superimposed and bonded.
