Beschreibung
Zusammenfassung:	A gas-insulated switchgear (1) includes, inside an airtight container with insulation gas sealed therein, a fixed-side electrode (11), and a movable-side electrode (12) which is driven by a driving mechanism attached to the airtight container so as to contact/separate with/from the fixed-side electrode (11), the gas-insulated switchgear (1) including: a first magnetic body provided on an inner side from an outer periphery of the fixed-side electrode (11); a second magnetic body having a tubular shape and surrounding the fixed-side electrode (11); and a current-conduction terminal (15) provided at an outer periphery of the movable-side electrode (12), wherein at least one of the first magnetic body and the second magnetic body is a magnet magnetized in a direction in which the movable-side electrode (12) is movable.
