Oscillator

Abstract

An oscillator includes a resonator element, an oscillation circuit configured to cause the resonator element to oscillate, a temperature control element configured to control a temperature of the resonator element, a plurality of temperature sensors, a failure detection circuit, and a container configured to accommodate the resonator element, the oscillation circuit, the temperature control element, the plurality of temperature sensors, and the failure detection circuit. The failure detection circuit performs failure detection for the plurality of temperature sensors and the temperature control element based on output values of the plurality of temperature sensors in a state where the temperature control element operates.
