A contact device according to the present disclosure includes: a metal container having a through hole and an opening; a pipe lead inserted into the through hole; an insulating material that seals the metal container and the pipe lead; and a terminal base made of a low-resistance metal, the terminal base penetrating the pipe lead and being fixed to the pipe lead. The pipe lead has a fragile portion that relieves external stress.

Hermetic terminal and contact device using the hermetic terminal

According to a hermetic terminal based on the present invention, a hermetic terminal () to be hermetically fixed to an aluminum electrolytic capacitor () includes: a base () which has a through hole, is to be attached to a case () of the aluminum electrolytic capacitor (), and is made of a composite material having electrical conductivity; at least one lead () which is inserted into the through hole of the base (), and is made of a composite material having electrical conductivity; and an insulating glass () which hermetically seals a gap between the base () and the lead (). Surfaces of portions of the base () and the lead () which come into contact with an electrolytic solution within the case () are composed of a metal material having corrosion resistance to the electrolytic solution.
