Abstract
A vacuum interrupter is equipped with a vacuum container and fixed and movable electrodes provided in the vacuum container. The vacuum container is constructed by hermetically respectively joining fixed-side and movable-side end plates to one and the other end portions of an insulating tube. The insulating tube is equipped at its end portion with a projection portion that projects in an axial direction of the insulating tube along an outer periphery of the insulating tube. The insulating tube is equipped at its end portion with an end plate joining portion that projects from a base end portion of the projection portion inwardly in a radial direction of the insulating tube. The end plate joining portion is equipped on its surface with a metallized layer to which the fixed-side or movable-side end plate is joined by brazing.
