A gas-insulated switchgear (91-97) includes a fixed-side electrode (10) and a movable-side electrode (20) facing each other in a container filled with an insulating gas. The fixed-side electrode (10) includes a tubular fixed-side conducting contact (11) and a fixed-side shield (12) for housing the fixed-side conducting contact (11). The movable-side electrode (20) includes a movable conductor (21) driven by a driving unit to be connected to and separated from the fixed-side conducting contact (11). The gas-insulated switchgear (91-97) includes a fixed-side arc shield (13) in the form of a circular plate. The fixed-side arc shield (13) is made of an arc-resistant member and has an opening (13x) of a diameter larger than the outer diameter of the movable conductor (21), the opening (13x) being formed on the side of the fixed-side shield (12) facing the movable-side electrode. The fixed-side arc shield (13) is formed into a thin plate so that the fixed-side arc shield (13) causes an arc current to flow outward in a radial direction during contact parting of the fixed-side conducting contact (11) and the movable conductor (21) to generate magnetic flux on a surface thereof in a circumferential direction that produces a force acted on an arc in the direction of a central axis, thereby restricting the arc in the vicinity of the opening (13x).
