Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a gas insulated bus which is small high in economical efficiency and advantageous in reducing the mounting area and the volume of a building, when it is formed as part of a gas insulated switchgear. SOLUTION: The length between flanges F1, F2 on both ends of a bellow coupling is fixed at a given length L by a stud 11, nuts 14, 15, 16. The flanges F1, F2 are fixed to T-shaped tank flanges T21, T22 by studs 12, 13 so as to sandwich insulating spacers SP21, SP22. A groove 53, in which an adhesive 53a is inserted, is formed in the flange F1, and a cover 54 bolted on the end surface of the flange F1 holds airtightness from the outside. A gas valve 51 is mounted on a hole 55 formed in the flange F1, so that gas piping may be connected in a vertical direction to a flange surface.
