Abstract
An atomic oscillator includes a light source unit including a light source and a first temperature control device controlling the light source to have a first temperature, an atom cell unit including an atom cell accommodating an alkali metal atom and that light emitted from the light source enters and a second temperature control device controlling the atom cell to have a second temperature different from the first temperature, and a container accommodating the light source unit and the atom cell unit and has a first surface and a second surface different from the first surface. The light source unit is mounted to the first surface, and an air gap is present between the light source unit and the second surface. The atom cell unit is mounted to the second surface, and an air gap is present between the atom cell unit and the first surface.
