Abstract
An oscillator includes a resonator element, a first temperature sensor that measures a temperature of the resonator element, a temperature control element that controls the temperature of the resonator element, and a temperature control circuit that generates a control signal for controlling an operation of the temperature control element, in which the temperature control circuit generates the control signal based on a value obtained by multiplying a difference between a set temperature and a first measured temperature measured by the first temperature sensor by a gain, and the gain is variable.
