Abstract
A structure of an electrode unit for applying electricity to a conductible substance (4) installed in a metallic housing (2) has a metallic electrode (6) connected to a portion of the conductible substance (4), an insulating member (8, 8') positioned between the electrode (6) and the metallic housing (2), and a metallic sealing material (10,10') to be transformed by fastening a nut so as to secure sealability between the electrode (6) and the insulating member (8) and between the metallic housing (2) and the insulating member (8). The structure of an electrode unit is excellent in an insulating property and a gas sealability between the metallic housing (2) and electrode (6) and therefore has high reliability.
