Abstract

PURPOSE:To suppress the sub-oscillation, by providing the main and auxiliary electrode at the front and rear side of oscillator and suitably connecting them. CONSTITUTION:The auxiliary electrode 5, 5' are newly provided along the circumference of the main electrode 2, 2' of the front and rear side of crystal oscillator, and the main electrode on the front surface and the auxiliary electrode 5' on the rear side, and the main electrode 2' on the rear side and the auxiliary electrode 5 on the front surface are respectively conducted. Thus, the energy of sub-oscillation of the specific group remained in the main electrode and that present at the part other than the main electrode on the plate are electrically cancelled each other to suppress the sub-oscillation of the specific group.
