To provide a gas-insulated switchgear including a metal tank 1 that is grounded and has insulating gas filled therein, a central conductor 2 that is extended in the tank 1 and to which an alternating voltage is applied, an insulative coating film 101 that is coated on an inner surface of the tank 1, and a coating film 3 that is overcoated on the coating film 101 and is formed by coating a coating material containing an insulative coating material component and a non-linear resistance material. Due to this configuration, behavior of metallic foreign matter can be suppressed in a wide range from a region having a small electric field to a region having a high electric field. |
