摘要:
An alkali-encapsulated cell internally having an alkali metal vapor G encapsulated is provided with first and second heaters 11, 12. The alkali-encapsulated cell 10 has first and second end faces 10a, 10b opposed to each other, and a side face 10c connecting the two end faces 10a, 10b. Each of the first and second heaters 11, 12 has a covering portion 11B, 12B and an extending portion 11C, 12C. Some portions of the alkali-encapsulated cell 10 are inserted in the covering portions 11B, 12B. On the other hand, the extending portions 11C, 12C extend in directions away from the alkali-encapsulated cell 10. The first and second heaters 11, 12 are separated from each other with a distance d0 between them in an opposing direction of the first and second end faces 10a, 10b.
