Abstract
An atomic cell includes: metallic atoms; a body portion having a through hole; window portions that are bonded to the body portion and form an inner space where the metallic atoms are sealed together with the body portion; a communication hole that communicates with the inner space and forms a groove and a hole; and a sealing portion that is disposed at a position that overlaps a bonding portion of the body portion and one window portion in a plan view seen in a direction where the body portion and the window portions are overlapped and blocks the communication hole by fusion.
