PROBLEM TO BE SOLVED: To reduce the generation of a trouble such as a zero-point shift and the like by preventing a liquid (water) from intruding from an introduction part at low cost with a simple structure.SOLUTION: A plate surface is made to intersect at a right angel in the passing direction F of a measurement fluid between an introduction part 10A of the measurement fluid and a sensor diaphragm 32, and a first baffle (first stage baffle) 71 and a second baffle (second stage baffle) 72 are arranged to be opposed to each other. The first baffle 71 is arranged in the upstream side of the passing direction F of the measurement fluid than the second baffle 72, and the second baffle 72 is arranged in the downstream side of the passing direction F of the measurement fluid than the first baffle 71. Further, the first baffle 71 has an opening 71a formed in the central part only of the plate surface, and the second baffle 72 has one or more openings 72a formed in the peripheral part of the plate surface. |
