Abstract
A conductive coating layeris formed on at least one of an inner peripheral side and an outer peripheral side of a base bodyof bellowsby diffusion-bonding. Regarding the diffusion-bonding, the flat conductive coating layeris layered on at least one end surface side of the plate-shaped base body, and these base bodyand conductive coating layerare diffusion-bonded. After forming this diffusion-bonded multilayer member into a tubular body by a drawing process, a side wall of the tubular body is formed into a bellows shape. With these processes, it is possible to obtain the bellows that has the conductive coating layer having a more uniform thickness on the base body of the bellows and has extremely good characteristics (the mechanical characteristics and the electric characteristics).
