Abstract
An atomic oscillator includes a light source; an atomic cell in which alkali metal atoms are contained and on which light that is emitted from the light source is incident; a first coil that applies a magnetic field to the atomic cell; a first shield that contains the atomic cell and the first coil and shields a magnetic field; a second shield that includes a first member having a recess and a second member, containing the light source and the first shield in a space which is formed by the first member and the second member, and the second shield shields the magnetic field; and a second coil that generates a magnetic field passing through an opening of the recess.
