Claims

[Scope of utility model registration request]

Insulating plates are respectively fixed to the upper and lower surfaces of an insulating frame that surrounds a piezoelectric plate with electrodes formed on both the upper and lower main surfaces, and a conductive protrusion provided on one of these insulating plates and a conductive protrusion on the other. The piezoelectric plate is held between the insulating plate and the bellows of a leaf spring interposed between the piezoelectric plate so as to be able to vibrate from above and below, and the protrusion is attached to the side surface of the frame by an extraction electrode having the protrusion formed on the insulating plate. A chip characterized in that, while being pulled out, the leaf spring is pulled out to another side surface of the frame body using a pull-out electrode formed on the other insulating plate, and the pull-out electrode is electrically connected to terminal electrodes formed on each of these side surfaces. shaped piezoelectric resonator.
