Claims

[Scope of utility model registration request]

Two piezoelectric substrates are provided in which vibrating electrodes are respectively formed on opposing main surfaces, a connecting electrode is drawn out from one of these vibrating electrodes, and an extraction electrode is drawn out from the other in a direction different from the direction in which the connecting electrode is drawn out. The piezoelectric substrate is bonded with a conductive member provided so as to surround the vibrating electrode and intersect with the connecting electrode, with the main surfaces on the connection electrode formation side facing each other, leaving a vibration interval, and the conductive member connects the piezoelectric substrate. While the terminals are electrically connected to each other, an insulating cover is supported by the insulating cover and the terminal electrode formed on the side surface of the piezoelectric substrate, leaving a vibration interval of the piezoelectric substrate on the main surface of the lead-out electrode type side of the piezoelectric substrate. and a piezoelectric resonator in which the lead electrodes of the piezoelectric substrate are electrically connected to these terminal electrodes.
