Abstract
A gas electrical apparatus includes: a container filled with insulating gas; a high voltage conductor arranged inside the container and applied with a prescribed voltage; and an insulating support member configured to insulate and support the high voltage conductor relative to the container. The high voltage conductor is covered by a first dielectric film. The first dielectric film includes a through hole extending from the first main surface to the second main surface. The through hole has an inner circumferential surface on which a first coating film is formed such that at least a hole diameter of the through hole is less than a diameter of an electron avalanche in a state where a gas insulated electrical apparatus is used.
