ABSTRACT:
A configuration for forming a gastight space is prevented from being projected from a housing, so that a projection is not formed on the housing. A sealed contact device includes a housing including a container body having an opening end portion, the container body being made of ceramics, a metal lid connected to the opening end portion to form a gastight space, a stationary contact and a movable contact disposed in the container body, and a sealed vent portion formed in the metal lid, in which the sealed vent portion is formed by sealing a vent hole formed in the metal lid after exhausting a gas in the gastight space and supplying a desired gas into the gastight space, via the vent hole.
