PROBLEM TO BE SOLVED: To provide a minute bubble generator, capable of increasing white turbidity of bathwater or the like. SOLUTION: Gas-liquid dissolved fluid in which gas is pressurized and dissolved in liquid is pressure-released by a pressure decreasing means to generate minute bubbles to be injected from a delivery nozzle 30 to be delivered. On the delivery nozzle 30, a plurality of venturi tubes 12b are provided in parallel as the pressure decreasing means, and an intersectional part of a conduit inner wall surface 12d of a delivery port 12c of each venturi tube 12b with a delivery outer end surface 12e is formed in a curved surface 12g. In this constitution, generation of eddy currents and following backflow is hard to occur around the delivery port 12c, but delivered bubbles are uniformly diffused to run. The bubbles are thus prevented from being combined with each other, thereby the white turbidity of bathwater or the like is increased. COPYRIGHT: (C)2008,JPO&INPIT
