Summary:A gas circuit breaker having a single supporting structure easy to be inspected. The gas circuit breaker includes: a grounded tank in which a gas is enclosed; a fixed contact contained in the tank; a moving contact contained in the tank and electrically connected to the fixed contact; an insulating grounded support for supporting the moving contact in a state that the moving contact is insulated from the tank; an inter-contact insulating tube for supporting the fixed contact in such a manner that the fixed contact is insulated from the moving contact; an in-bushing conductor connected to the side of the fixed contact; an in-bushing conductor connected to the side of the moving contact; and a maintenance cover removably provided on a side end portion of the tank. The gas circuit breaker further includes a fixed contact side conductor mounted on the fixed contact; and a connecting conductor, mounted on the fixed contact side conductor, for slidably supporting the in-bushing conductor, wherein a hole which allows the connecting conductor to be moved in the axial direction of the in-bushing conductor is formed in the fixed contact side conductor.
