Abstract

Providing an OCXO having a highly stabilized output frequency. In an oscillator, which is an OCXO, crystal resonators, oscillator circuits, a temperature detector, and a heater circuit are disposed inside a first container, which is supported in a state of floating inside a second container, while a voltage stabilizer circuit for stabilizing a supply voltage supplied to the heater circuit is disposed apart from the first container inside the second container. Therefore, the supply voltage supplied to the heater circuit is stabilized. The voltage stabilizer circuit is less likely to be affected by heat generation of the heater circuit, thus obtaining a stable oscillation frequency output regardless of the environmental temperature.
