を特徴とする圧電音叉型振動子。[Claims for Utility Model Registration] A tuning fork portion is formed by carving three substantially parallel slits in one end of a piezoelectric substrate, and a substantially U-shaped electrode is formed along the central slit. Split electrodes are formed on both sides of the approximately U-shaped electrode,
In a piezoelectric tuning fork type vibrator in which a terminal portion integral with the divided electrode is formed in a non-vibrating portion and is covered with an exterior material, the terminal portion of both divided electrodes is connected to a common lead-out terminal connected to both terminal portions. The outer periphery of the piezoelectric substrate is covered with a dip so that the tuning fork portion of the piezoelectric substrate is short-circuited and the periphery of the tuning fork portion thereof is not in contact with the piezoelectric substrate, and the lead-out portion of the common lead-out terminal is protruded to the outside from the sheathing material. Piezoelectric tuning fork type vibrator.
