Claims

[Scope of utility model registration request]

Vibrating electrodes are formed to face each other on both the front and back sides of the piezoelectric substrate, and a terminal lead-out electrode is extended from each vibrating electrode toward the piezoelectric base end on the opposite side, and faces the terminal lead-out electrode with the piezoelectric substrate in between. A piezoelectric resonator characterized in that a vibrating electrode and a separate capacitive electrode are formed in this manner.
