PROBLEM TO BE SOLVED: To provide an electrostatic spray nozzle preventing electric shock accidents by making electrodes completely waterproof covered state, causing no drop of voltage due to leakage. SOLUTION: In the electrostatic spray nozzle, an electrode 14 is arranged in the vicinity of the spraying port 12a of the nozzle body 12 to electrically charge sprayed fluid b of the ground electric potential with a high voltage applied by the electrode 14. A nonconductive cover 13 covering the outside of the nozzle body 12 comprises a cylindrical cover body 18 fixed to the nozzle body 12 side and a cylindrical end cap 19 externally engaged in the end side of the cover body 18. The cylindrically formed electrode 14 is set between the engaging faces of the cover body 18 and end the cap 19, and waterproof seals 20 are arranged between the engaging faces of the cover body 18 and the end cap 19 at the positions of both sides holding the electrode 14.
