PROBLEM TO BE SOLVED: To provide a spray gun for electrostatic coating which has small load on workers, is small-sized and lightweight and safely used in the operation and by which resources are saved and environmental pollution is reduced. SOLUTION: In the spray gun for electrostatic coating having a high voltage generator 5 and treating the side of a coating material as earth potential, a discharge electrode 35 and an earth electrode 36 opposed to the discharge electrode 35 is provided within a compressed air passage 9 for jetting, compressed air passed through the electrodes is ionized and jetted from an air cap 20 as jetted air and a charge electrode 6 is arranged in a zone not reaching a spray zone in the outside of a central air port 21 of the air cap 20 arranged in the outside of the coating material spray port 26.
