PROBLEM TO BE SOLVED: To provide a microbubble generating nozzle for generating sufficiently clouded microbubbles by further micronizing microbubbles generated by a pressure reduction mechanism and stabilizing the generation of the microbubbles over a long period of time. SOLUTION: The microbubble generating nozzle 4 is provided with an inlet 2, an outlet 3, the pressure reduction mechanism 13 and a plurality of venturi parts 40. Pressurized hot water in which air is pressurized and dissolved in hot water sucked from the inlet 2 is delivered from a plurality of pressure reduction nozzles 34 of a pressure reduction nozzle forming body 12 to a pressure reduction space 39, the microbubbles are generated by the sudden pressure reduction, and the hot water containing the microbubbles generated in the pressure reduction mechanism 13 is appropriately reduced in pressure in the plurality of venturi parts 40, further micronized by cavitation, and discharged from the outlet 3 into a bathtub 1.
