Abstract
An oscillator includes a vibrator element, a container in which the vibrator element is housed, at least one of a heating element and a cooling body configured to control the temperature on the inside of the container, an oscillation circuit electrically connected to the vibrator element, a D/A conversion circuit configured to control a frequency output by the oscillation circuit, and a reference-voltage generation circuit configured to supply a voltage to the D/A conversion circuit. The reference-voltage generation circuit is mounted on the inside of the container or on a substrate on which the container is mounted.
