There is provided a temperature-compensated crystal oscillator for reducing a voltage noise of a cubic function control voltage controlling an output frequency of an oscillation circuit. A temperature-compensated crystal oscillator includes a quartz vibrator, an amplifier having an oscillation frequency controller, and a temperature compensation circuit of a crystal oscillation frequency, wherein a reference voltage for a compensation voltage of the temperature compensation circuit is generated using a forward voltage of a diode.
