Abstract
An atomic oscillator includes: an atom cell in which alkali metal atoms are accommodated; a light-emitting element that emits light beams for exciting the alkali metal atoms toward the atom cell; a shield that includes a first member, a second member, and a high thermal resistance portion and accommodates the atom cell, the first member and the second member being members having a magnetic shielding property, and the high thermal resistance portion being provided between the first member and the second member and having a thermal resistance higher than thermal resistances of the first member and the second member; a temperature control element that controls a temperature of the first member; a heater that is thermally coupled to the second member; and a light-receiving element that receives light beams passing through the atom cell.
