Abstract
A gas cell to be filled with alkali metal atoms includes wall surfaces formed using a compound having polar groups or a material containing the compound, a first coating layer as a coating layer that coats the inner walls, formed using first molecules having functional groups to be chemically bonded to the polar groups and non-polar groups, and a second coating layer formed using non-polar second molecules on the first coating layer.
