Summary:PROBLEM TO BE SOLVED: To provide a vacuum circuit breaker which can ensure a contact area between a flexible conductor and a moving rod and finely energize between both, reduce the axial deflection of the moving rod when moving in a rod axis direction, be downsized, and improve reliability.SOLUTION: A vacuum valve body 10 in which a fixed electrode attached to a fixed rod 12 and a moving electrode attached to a moving rod 13 are oppositely disposed in an insulation cylinder body 11, is used. The fixing rod 12 is connected to one terminal conductor plate 14. The moving rod 13 projected out from the vacuum valve body 10 can move in a rod axis direction while coupling with an insulation operating rod 18 driven and controlled by a controller. A flexible conductor 16 electrically connects the moving rod 13 and the other terminal conductor plate 15. An energization connecting block 17 made by well conductive material is fitted with an outer surface of the moving rod 13 so as to apply power, and one end of the flexible conductor 16 is adhered on lower end surfaces of the moving rod 13 and the energization connecting block 17.
