Abstract: A resin-molded vacuum valve has an internally hermetically sealed vacuum vessel, a fixed axis having a fixed electrode at one end thereof, and a movable axis having a movable electrode at one end thereof and facing the fixed axis in the vacuum vessel. The fixed and movable electrodes are fixedly and movably attached, respectively, to respective ends of the vacuum vessel with a contact therebetween. Further, a conductor connected to the fixed axis extends from a pull-out opening. First, second, and third electric field concentration alleviating shields are disposed near the fixed axis, near the movable axis, and near the pull-out opening, respectively. Buffer layers cover the outer peripheries of the vacuum valve and the conductor, and a resin insulator allows the movable axis to be movable, and buries and fixes the fixed axis, the vacuum vessel, the conductor, the buffer layers, and the electric field concentration alleviating shields.
