PROBLEM TO BE SOLVED: To provide a technology capable of notifying the exterior of a time point when an oscillation frequency of an oscillation device after power-on is stabilized, with high accuracy, in an oscillation device including an oscillator with a constant-temperature bath.SOLUTION: A device is configured to have: a heater for maintaining a temperature of an atmosphere in which a piezoelectric vibrator configuring an oscillation circuit is provided to a setting temperature; a temperature sensor detecting the temperature of the atmosphere and outputting a corresponding signal; a control circuit notifying the exterior of that an oscillation frequency outputted from the oscillation circuit is stabilized after receiving from the temperature sensor a first detection signal indicating that the temperature of the atmosphere becomes the setting temperature by the heater, after power-on; and a storage part storing correspondence between a second detection signal outputted from the temperature sensor to the control circuit at power-on, and a delay time from when the control circuit receives the first detection signal to when the notification is performed. |
