Zusammenfassung:	PROBLEM TO BE SOLVED: To reduce the amount of a getter agent enclosed in an internal space with Na.SOLUTION: A Na supply device includes a storage system device S for storing Na, and a Na injection system device I for injecting Na stored in the storage system device S into a space 4a of a valve body 5 from an injection port 5a of the valve body 5 while purging an inert gas around the valve body 5. The storage system device S has a Na storage tank 10 for storing Na and Ti powder as a getter agent for removing impurities in tank contents including Na by combination, and a heater 14 for heating the tank contents.
