Abstract: A vacuum interrupter comprises a vacuum container which includes an insulation tube made of ceramics and having openings at both ends thereof, and sealing metals for hermetically sealing the openings respectively. In the vacuum container, a pair of contacts are disposed so that these contacts can detachably contact to each other. The composition of the material constituting at least one of the sealing metals comprises 25 to 55 wt % of Ni, 0.02 to 1.0 wt % of Si and substantially the residual amount of Cu. Preferably, the composition further comprises 0.02 to 1.5 wt % in total of Si and Mn and/or 5.0 wt % or less in total of Fe and Co.
