Abstract: In order to remove external noise of the same phase, such as a power supply noise, on an crystal oscillator, one oscillation output has been conventionally obtained from one oscillation circuit, and by using a differential amplifier, the one oscillation output is turned into two oscillation outputs that are 180 degrees out of phase. However, it has been impossible to remove the noise of the same phase that occurs in the oscillation circuit. According to the present invention, there is provided a piezoelectric oscillator including a piezoelectric vibrator, and first and second oscillation circuits, and comprising a configuration such that an input terminal of the first oscillation circuit and one terminal of the piezoelectric vibrator are connected, an input terminal of the second oscillation circuit and the other terminal of the piezoelectric vibrator are connected, characterized in that: oscillation outputs that are 180 degrees out of phase to each other are obtained from outputs of the first and second oscillation circuits.
