<p>PROBLEM TO BE SOLVED: To provide a quantum interference device and an atomic oscillator which can make the magnetic field produced smaller by energization to a heating part while reducing the power consumption, and to provide an electronic device and a movable body, each of which is superior in reliability and has such a quantum interference device.SOLUTION: An atomic oscillator of the present invention comprises: a gas cell having an internal space in which metal atoms are sealed; a heating part driven by an electric power supply, and operable to heat the gas cell; a power source terminal; and a step-up circuit operable to raise a voltage output from the power source terminal, and applied to the heating part. The step-up circuit has a function of a switching regulator, of which the switching frequency is 10 kHz to 10 MHz.</p> |
