PROBLEM TO BE SOLVED: To provide an apparatus for detecting the flow rate of grain by detecting the impact force of grain to a colliding plate by a load measuring sensor, with which a small-sized and inexpensive load measuring sensor such as a pressure-sensitive sensor, etc., is used and the troubles of the sensor caused by collision with grain and dust in a grain flow path are avoided. SOLUTION: The apparatus 100 for detecting the flow rate of grain includes the colliding plate 101 colliding with grain in the inside of the grain flow path, a rotary member 102 to which the impact force acting on the impinging plate 101 is transmitted as a rotary force, a fulcrum shaft 103 for rotatably supporting the rotary member 102, and the pressure-sensitive sensor 104 for detecting the rotary force of the rotary member 102 at the outside of the grain flow path.
