PROBLEM TO BE SOLVED: To provide a water spraying nozzle capable of making strong magnetic forces act on spray water while spraying the water on plant cultivation soil such as a farm and a flowerpot. SOLUTION: A trumpet-shaped nozzle head 3 connected to the one end of a water introducing pipe 1 forming a handle part and of which the diameter expands gradually toward the other end is provided. A perforated plate 4 formed by boring a plurality of discharge holes 5 is installed on the other end of the nozzle head 3. A magnetic field generator 7 is particularly housed in the nozzle head 3 for exposing flow-water passing through the inside of the nozzle head 3 to magnetic force lines. The magnetic field generator 7 is constituted of a cylindrical holder 10 embedded inside the nozzle header 3 and in which a flowing passage 6 for the flow-water is formed, a pair of plate-shaped magnets 8A, 8B fixed with the magnetic heteropoles facing each other in the inside periphery of the holder 10 forming the flowing passage 6, and annular magnetic plates 12 and ring magnets 9 embedded alternately in the inside periphery of the holder 10 adjacent to the plate-shaped magnets 8A, 8B. The surfaces of the same pole are faced each other by pinching the magnetic plates 12 with the respective ring magnets 9.
