PROBLEM TO BE SOLVED: To provide an economical gas insulation bus line with good anti- earthquake characteristics. SOLUTION: A base unit 10 includes a gas insulation linear unit 11 with a given length, and a gas insulation bent unit 12 joined with an end of the linear gas unit 11 and bent at an angle of 15 deg. or above with respect to an extended line in an elongated direction of the linear unit 11. A plurality of the base units 10 are so connected that each bent unit 12 is arranged on the same plane in almost parallel with a mounting face to form an almost linear gas insulation bus line. The given base unit 10 is fixed to a frame stage on the mounting face. At the same time, the other base unit 10 is provided on the other frame stage in a way that the base unit 11 can be moved in a direction almost parallel with the mounting face thereof.
