Abstract: In this urine flow meter, a water wheel which is caused to rotate by a flow of urine from a urine flow passage tube is provided at a lower end side of the urine flow passage tube. The shape of a tip portion of the urine flow passage tube that causes urine to hit on the water wheel constitutes a nozzle part in which the tip-side is acutely processed, and an opening is formed in a sidewall surface of the tip-side. A guide is provided in a urine flow passage and is disposed in such a way that a tip of the guide is elongated as far as a tip-side region of the mine flow passage tube. The water wheel is caused to rotate by the flow of urine, and the urine flow rate can be detected on the basis of the rotation detection information.
