PROBLEM TO BE SOLVED: To provide a drip infusion measuring sensor which is inexpensive, can be miniaturized, and allows a nurse or others to easily and precisely carry out the measurement.SOLUTION: The drip measuring sensor 1 attachable to a drip cylinder 3 of a natural-drop-type drip set 2 has a body case 4 attachable to the drip cylinder 3, and a sensor part 5 arranged in the body case 4 for detecting or measuring the drop or the number of drops of infusion liquid naturally dropping through the drip cylinder 3. The body case 4 has a groove 4a capable of accommodating the drip cylinder, and an elastic holding member 16 arranged in the groove 4a and detachably fitting the drip cylinder 3 when accommodating the drip cylinder 3. Further, the sensor part 5 has a light emitting part 5A and a light receiving part 5B arranged while facing each other at positions to avoid the elastic holding member 16 on both the sides of the drip cylinder 3 accommodated in the groove 4a.
