Zusammenfassung:A stator includes a magnetic plate material that has a main plate surface that is a surface to face a main plate of a movement when assembled to the main plate and that has a rotor accommodating hole formed in a part thereof; and a non-magnetic region that is made non-magnetic by applying chromium on the main plate surface around the rotor accommodating hole and irradiating the chromium with a laser from the main plate surface side.
