PURPOSE: To provide an electrostatic spraying device capable of homogeneously and efficiently coating a coating object to a wide area of the object well charging powder material and decreasing the ion streams heading toward the coating object.

CONSTITUTION: The electrostatic spraying device 1 for electrostatically spraying powder material used for electrostatic coating is provided with an ionizing head 16 having an annular ejection port 2 formed by coupling of a deflector 58 constituting a charging electrode and a bowl-type member 56 so as to have a prescribed spacing in such a manner that this head is rotated by a turbine 14 driven by compressed air. The ionizing head 16 is provided with a counter electrode 54 backward in the axial direction as an ion trap. The powder is sent together with air, is passed through the ionizing head 16 and is evenly charged and ejected by the ejection port 62. Many of the simultaneously ejected ions are absorbed into the counter electrode 45.
