A gas-insulated switching device includes a bus bar-connecting conductor, within a cylindrical container, which connects one end of a circuit breaker portion, disposed wihtin the container, to a main bus bar mounted on the outer side of the container. The bus bar-connecting conductor is inclined relative to the axis of the container in such a manner that one end of the bus bar-connecting conductor connected to the main bus bar is situated closer to the other end of the breaker portion than to the one end of the breaker portion, and radially more outwardly of the breaker portion than the other end of the bus bar-connecting conductor connected to the one end of the breaker portion. As the bus bar-connecting conductor is inclined in the above manner, the device can be of a compact size without possibility of affecting the insulation between the bus bar-connecting conductor and the other end of the breaker portion by the voltage applied therebetween in the open or circuit-breaking state of the breaker portion.
