摘要：PROBLEM TO BE SOLVED: To provide gas-insulated device having a fastening structure of an insulating support, which prevents cracks or destruction of the insulating support due to infiltration of water and which also is high in workability. SOLUTION: In the gas-insulated device, an insulating spacer 1 to insulate and support the center conductor 20, located inside metal tanks 2, 3, is interposed between two flanges 2a, 3a provided at mutual connection ends of metal tanks 2, 3, respectively, into which insulating gas is sealed, and a fastening structure is provided to fasten the flanges 2a, 3a by a fastening means including a bolt 7 to pass through the flange 3a through the insulating spacer 1 from the flange 2a. In a through-hole 4b of the bolt 7 made in the insulating spacer 1, for example, a sheet-like elastic member 10 which is expanded by absorbing water is disposed at an air gap part 9b formed between the bolt 7 and the insulating spacer 1.
