In a porous pitot tube, the direction and speed of the flow are measured by inserting a cylindrical body into the flow and detecting the pressure introduced from the pressure measurement hole provided on the outer wall of the cylindrical body. A porous pitot tube characterized in that pressure measuring holes are provided at equal intervals in a circumferential cross section at six or more locations and at most eight locations.
