Abstract:
A piezoelectric resonator device is provided with a piezoelectric resonator plate, and first and second sealing members that hermetically seal driving electrodes formed on the piezoelectric resonator plate. The piezoelectric resonator plate and the first sealing member are bonded together with a bonding material, and the piezoelectric resonator plate and the second sealing member are bonded together with a bonding material. Also, a multiple-surface bonding portion and a spread preventing portion are provided in at least either of a bonding area between the piezoelectric resonator plate and the first sealing member and a bonding area between the piezoelectric resonator plate and the second sealing member, the multiple-surface bonding portion allowing a bonding material to be bonded to multiple surfaces of different surface orientations, and the spread preventing portion being located on an outer side of the multiple-surface bonding portion and preventing a bonding region bonded to the bonding material from being enlarged.
