PROBLEM TO BE SOLVED: To clamp a gasket uniformly with a proper designed clamping margin. SOLUTION: The ring-shaped gasket 9 and a stopper 10 are interposed between the back surface of an electrode part 4a and the inner circumferential surface (surface of a lining 3) of a measuring tube 1, and a shaft part 4b is projected to the outer circumferential surface of the measuring tube 1 through a through-hole 6 provided in the measuring tube 1, and a nut 8 is clamped through a pedestal 7 onto the shaft part 4b projecting to the outer circumferential surface of the measuring tube 1, to thereby mount a signal electrode 4 on the inner circumferential surface of the measuring tube 1. The stopper 10 is a member requiring a greater reaction than the gasket 9, and further, the thickness t1 of the stopper 10 is set to be thinner than the thickness t2 of the gasket 9.
