PROBLEM TO BE SOLVED: To provide a vacuum switch capable of being downsized by making small an insulation distance with other parts (for instance, an outside part such as an interface). SOLUTION: The vacuum switch comprises a vacuum valve 17 consisting of a fixed electrode 2 formed at an upper part, a movable electrode 3 formed at a lower part freely in and out of contact with the fixed electrode 2, and a vessel 16 containing the fixed electrode 2 as well as the movable electrode 3 inside, a conductor part 6 electrically connected to the fixed electrode 2 outside the vacuum valve 17 and fixed to the vacuum valve 17, a protecting part 8 formed for covering a whole of the vacuum valve 17 and the conductor part 6 and insulating the same 17, 6 from the outside, and a fixed side terminal 7 arranged in penetration of a conductor through-hole 6a penetrating the conductor part 6 in a direction crossing a contacting and separating direction and a fixed side through-hole 8a formed at the protecting part 8 communicating with the conductor through-hole 6a, led out outside the protecting part 8, and electrically connected to the conductor part 6.
