An electrostatic spray gun wherein the barrel is formed by two tubes which define an annular gap for gaseous or pulverulent material. An electrode is installed in the inner tube between the front and rear ends of such tube and has two or more prongs extending outwardly into the gap. The central portion of the electrode has one or more discharging portions in a path for the flow of pulverulent or gaseous material toward a deflector which is releasably mounted at the front end of the inner tube. The electrode is connected with a high-voltage conductor which is mounted in a tubular shield within the inner tube.
