PROBLEM TO BE SOLVED: To provide an electrostatic sprayer for spraying a liquid to which voltage is applied, from a nozzle, wherein the gas-liquid boundary surface of the liquid discharged from the nozzle is stabilized to prevent the disorder of the spray direction. SOLUTION: The electrostatic sprayer is constituted so that a swelled surface 3 swelled in the spray direction of the liquid is formed in the center part of the distal end of the spray nozzle of 2 of the electrostatic sprayer and a first nozzle hole 4 is provided on the swelled surface 3. The first nozzle hole 4 is provided in the center part of the swelled surface 3 and second nozzle holes 5 are provided along the virtual circumference around the first nozzle hole 4 with a certain interval.
