Abstract
It is desired to even further attempt to stabilize temperature in oscillator such as OCXOs (Oven Controlled Crystal Oscillators). A temperature controlling apparatus is provided. The temperature controlling apparatus includes: a temperature sensor; a power supply circuit that supplies, to a first heater, power corresponding to a difference between a target value and a detected value obtained from the temperature sensor; and a second heater that is provided at a position such that thermal conduction therefrom to the temperature sensor is faster than that from the power supply circuit, and changes power consumption of the second heater according to power consumption of the power supply circuit.
