PROBLEM TO BE SOLVED: To easily perform temperature control based on an actual temperature of a crystal vibrator and to reduce the number of components in a crystal oscillator with a thermostat using a temperature compensated crystal oscillator.SOLUTION: The crystal oscillator with the thermostat includes: the temperature compensated crystal oscillator including the crystal vibrator; a temperature control circuit including a heating element that is heated by power, and controlling heating in the heating element; and a container accommodating the temperature compensated crystal oscillator and the temperature control circuit therein. The temperature compensated crystal oscillator further includes an integrated circuit including an oscillation circuit, a temperature sensor and a temperature compensation circuit which performs temperature compensation in an oscillation frequency on the basis of a detection result in the temperature sensor. On the basis of the detection result of the temperature sensor provided in the integrated circuit, the temperature control circuit performs temperature control in such a manner that a temperature of the crystal vibrator is fixed. |
