Claims

[Claims for Utility Model Registration] Comprising a piezoelectric substrate and an insulating substrate having substantially the same shape as the piezoelectric substrate and sandwiching the piezoelectric substrate from both sides, two parallel slits are formed in the piezoelectric substrate, and A vibrating electrode part that generates thickness shear vibration is formed between the slits, and connecting electrode parts connected to the vibrating electrode part are formed at both ends, and a vibration space is created around the vibrating electrode part. A chip-type piezoelectric resonator characterized in that a piezoelectric substrate and an insulating substrate are adhesively fixed to each other through an adhesive in a state in which the piezoelectric substrate and an insulating substrate are left in place, and a part of a connecting electrode portion of the piezoelectric substrate is exposed to the outside in the adhesively fixed state.
