To obtain a vacuum switchgear enabling miniaturization of the entire device by simplifying an operation mechanism, and by making a necessary load constant when an electric current is supplied/cut off.

A double-break vacuum switchgear enables the electric current to be simultaneously supplied and cut off in a pair of series-connected cut-off parts. The pair of series-connected cut-off parts is perpendicularly connected to a connection conductor, and an operation means is perpendicularly connected to the center of the connection conductor in the longitudinal direction. The operation means serves as a symmetric axis for two pairs of cut-off parts, and in a state where the pair of cut-off parts is cut off, a gap between a movable electrode 5a and a fixed electrode 4a is formed larger (GinGout) as it goes away from the symmetric axis.
