Abstract
An atomic cell is filled with an alkali metal therein and includes an inner wall which is formed from a material containing a compound having a polar group, a first coating layer which coats the inner wall and is formed from a first molecule having a nonpolar group and a functional group that undergoes an elimination reaction with the polar group, and a second coating layer which coats the first coating layer and is formed from a nonpolar second molecule, wherein the second molecule is polypropylene, polyethylene, or polymethylpentene.
