A piezo-electric oscillator includes an oscillatory circuit including a piezo-electric resonator for generating an oscillatory signal, a buffer amplifying circuit for buffering and amplifying the oscillatory signal, the buffer amplifying circuit being connected serially with the oscillatory circuit, and a switching circuit for switching a power supply line. The switching circuit is connected in parallel with the buffer amplifying circuit and selectively short-circuits the buffer amplifying circuit in accordance with an output signal of the oscillatory circuit.
