Abstract
An oscillator includes a vibration element, an oscillation circuit configured to oscillate the vibration element and output an oscillation signal, a temperature sensor, a temperature compensation circuit configured to compensate for a frequency temperature characteristic of the vibration element based on an output signal of the temperature sensor. The vibration element is within a first case having a first atmosphere, and the oscillation circuit, the temperature sensor, and the first case are within a second case having a second atmosphere, whereby the first atmosphere has a higher thermal conductivity than the second atmosphere.
