PROBLEM TO BE SOLVED: To provide a vacuum valve which enables reduction in manufacturing time and enables confirming state of brazing between middle flanges and a shield from the outside after sealing. SOLUTION: The vacuum valve comprises; a vessel which is constituted by combining a first insulating envelope 1a and a second insulating envelope 1b; the flanges 10a and 10b disposed between the first insulating envelope 1a and the second insulating envelope 1b, which have supporting openings penetrating from their inside to the outside; a fixed electrode 7 disposed in the vessel; a movable electrode 8 disposed in the vessel, which can contact with and release from the fixed electrode 7; and a shield disposed covering a region where the movable electrode 8 contacts with the fixed electrode 7, which has a protruding rim 121 supported with the openings of the flange 10a and 10b by brazing.
