A multi circuit type vacuum switchgear with improved ground isolation reliability. The multi circuit type vacuum switchgear has plural main circuit switches in a chamber. The respective main circuit switches, each having a fixed electrode and a movable electrode open/close to the fixed electrode, are respectively accommodated in a non-earthed type vacuum chamber. The respective movable electrodes are connected with flexible conductors. Operating rods are introduced into the non-earthed type vacuum chamber and respectively connected to the respective movable electrodes via insulators. The vacuum switchgear has a molded part having a first insulating member to insulate the main circuit switches and a second insulating member, integrally formed with the first insulating member, to insulate the movable electrode side and the movable operating rod side. The molded part is provided on the periphery of the vacuum chamber.
