PROBLEM TO BE SOLVED: To improve the operational reliability of a urine flow measuring toilet bowl without the risk of causing a water leakage accident. SOLUTION: This urine flow measuring toilet bowl, which is adapted to measure urine flow information such as a urine quantity and a urine flow rate, includes: a bowl for receiving user's urine; a water supply means for washing the inside of the bowl and supplying a predetermined quantity of staying water to the interior of the bowl; a calibration curve storage means for storing the calibration curve relationship between a previously computed staying water level and the quantity of staying water; and a urine flow information computing means for computing the urine flow information including at least the quantity of urine discharged by a subject according to a change in the staying water level changed by discharged urine of the subject and the above calibration curve relationship, wherein the staying water level measuring means includes: an ultrasonic wave transmitting part installed on the outer wall surface side of the bowl for transmitting an ultrasonic wave toward the staying water surface; and an ultrasonic wave receiving part installed on the outer wall surface side of the bowl for receiving the ultrasonic wave reflected on the staying water surface, and the ultrasonic wave is transmitted through the wall surface of the bowl to measure the staying water level.
