The present invention provides a nozzle wherein adherence of water droplets around nozzle openings is prevented and a large quantity of mist is generated. The spray nozzle is provided with a first nozzle opening (3) disposed on a spray side tip above the center axial line of a nozzle main body (2) and a second nozzle opening (4) and a third nozzle opening (5) protruding more to the spray side than the first nozzle opening (3) and opposingly disposed at an incline so as to face each other toward the center axial line. The second and third nozzle openings (4, 5) are made round, and the first nozzle opening (3) is given an elongated circle or elliptical shape. A gas-liquid mixed fluid sprayed from the second and third nozzle openings (4, 5) and a gas sprayed from the first nozzle opening are made to collide above the center axial line (P) and ultrasonic waves are generated by the collision, thereby generating a large volume of fine mist. |
