Abstract:
1. A gas cell unit comprising: a gas cell in which a gaseous alkali metal atom is sealed; a first heating resistor that is heated by energization and heats the gas cell; and a second heating resistor that is heated by energization and heats the gas cell, wherein the first heating resistor and the second heating resistor face each other across the gas cell, a current flowing through the first heating resistor and a current flowing through the second heating resistor include current components flowing in a same direction, and a magnetic field generated in the gas cell by the energization to the first heating resistor and a magnetic field generated in the gas cell by the energization to the second heating resistor mutually weaken strengths of the magnetic fields in the gas cell, and each of the first heating resistor and the second heating resistor is rectangular when viewed in plane, and the current flows in a direction parallel to a short side.
