Disclosed is a medical fluid nozzle which makes fluid drops less likely to remain at its tip portion after the medical fluid is dropped. The medical fluid nozzle 1 is a substantially cylindrical shape with a tip surface formed in a substantially planar shape. An annular ridge 10 is formed along the circumferential direction at the tip portion of the medical fluid nozzle 1. The ridge 10 is formed so as to be continuous with the tip surface of the medical fluid nozzle 1 and has an extended surface 11 formed with an increased diameter so as to be flush with the tip surface of the medical fluid nozzle 1.
