PROBLEM TO BE SOLVED: To provide a fluid vibration-type flowmeter by which impurities contained in a fluid can be removed sufficiently and whose construction is sufficient by strong. SOLUTION: A semicircular pillar 8 in which a curved face part 8a formed in an arc shape is directed to the upstream side and in which a plane part 8b in the position of a string is directed to the downstream side is installed on the upstream side of a nuzzled flow passage 210. The semicircular pillar 8 is constituted of a porous member, and it is attached to a prescribed flow passage wall 110 via a holding means 9. The holding means 9 is formed integrally of a base part 91 which holds one end face of the semicircular pillar 8. The holding means 9 is formed integrally of a support part 92 which is erected and installed at the base part 91 and which holds the plane part 8b of the semicircular pillar 8.
