Abstract
A gas cell unit has a gas cell, inside which gaseous metallic atoms are sealed a first heater that heats the gas cell, and a second heater that is provided to face the first heater via the gas cell and heats the gas cell. The heaters include a first heating resistor and a second heating resistor which are provided so as to face each other, are heated by electric current flow, and mutually offset the magnetic fields generated along with the electric current flow.
