PROBLEM TO BE SOLVED: To provide a fountain nozzle having a simple structure and enabling the production of a fountain capable of performing the ejection of water in a specific posture like a sky rocket by impinging succeeding jet water against preceding jet water to scatter water and generating bursting. SOLUTION: The fountain nozzle 1 is constituted of the nozzle main body part 2 extending up and down, the U-shaped underwater bent pipe part 4 connected to the upstream side of the nozzle main body part 2 and sunk under the surface WL of the water of a spray pond 3 and the inverted U-shaped aerial bent pipe part 5 connected to the upstream side of the underwater bent pipe part 4 and projected above the surface WL of the water of the spray pond 3. The upstream end part of the aerial bent pipe part 5 can be connected to a water pipe 10A. Further, a drain valve 7 opened and closed on the basis of a fountain program is provided to the underwater bent pipe part 4 and an air supply valve 8 is provided to the aerial bent pipe part 5.
