PROBLEM TO BE SOLVED: To provide a vortex flowmeter receiving little influence even if the clearance between a pipe and a vessel is clogged with a foreign matter. SOLUTION: This vortex flowmeter measures a flow speed-flow rate by detecting a fluctuation in alternating pressure by a Karman vortex. The vortex flowmeter is characterized by having the vessel arranged in the pipe downstream of a vortex generator, and having a recessed part for setting rigidity higher in a side surface than a bottom surface, a pressure receiving plate having one end connected to the bottom surface, and receiving a fluctuation in the alternating pressure by the Karman vortex, and a detecting means for detecting deformation or a stress change of the bottom surface.
