PROBLEM TO BE SOLVED: To provide a liquid nozzle capable of effectively reducing an injection noise. SOLUTION: A mesh body 28 surrounding a periphery at a delivery side is provided on an inner surface 25a of the delivery side of a delivery hole of the liquid nozzle 18 with a clearance T with the inner surface 25a of the delivery side and a sound-absorption material 29 is arranged in the clearance T. The injection noise generated on the liquid nozzle 18 can be effectively reduced by synergizing reduction of the injection noise by the sound-absorption material 29 to reduction of the injection noise by the mesh body 28.
