PROBLEM TO BE SOLVED: To provide a switchgear not suffering from ground fault even in case a metal foil of a flexible conductor is damaged, through restraint of charged particle diffusion on switching current. SOLUTION: The switchgear is so structured that a toric oxygen-free copper terminal 13 arranged at one end part of a metal vacuum vessel 1 and having an inner diameter larger than an outer diameter of a movable electrode rod 7, and a disc-shaped oxygen-free copper terminal 15 arranged at the movable electrode rod 7 separately from the toric oxygen-free copper terminal inside the metal vacuum vessel 1 and having an outer diameter larger than the inner diameter of the toric terminal 13 and smaller than the maximum inner diameter of the metal vacuum vessel 1, are provided, and that a flexible conductor 16 is arranged between the toric and the disc-shaped terminals 13, 15.
