Abstract
An atomic oscillator includes: a light-emitting element; an atom cell that includes a first surface on which light beams from the light-emitting element are incident and a second surface from which the light beams incident on the first surface are emitted and accommodates alkali metal atoms in a gas state; a shield that accommodates the atom cell and has a magnetic shielding property, the shield having an opening; a heat transfer member that is in contact with a portion of the atom cell via an opening of the shield and has a thermal conductivity higher than a thermal conductivity of the atom cell; a temperature control element that is in contact with the heat transfer member and controls a temperature of the atom cell; and a light-receiving element that receives the light beams emitted from the second surface.
