In an electrostatic atomization coating apparatus including a nozzle head including a plurality of coating material ejection ports; a coating material chamber that is provided inside the nozzle head and to which a coating material is supplied via a coating material supply path, each of the coating material ejection ports being in communication with the coating material chamber via an individual branch coating material path; and a voltage application device that provides a potential difference between the nozzle head and an object to be coated, the coating material ejected from each of the coating material ejection ports via the coating material supply path, the coating material chamber, and the branch coating material path being brought into a charged state through application of a voltage by the voltage application device, an open/close valve device that opens and closes all of the branch coating material paths, or opens and closes a specific subset of a plurality of branch coating material paths out of all of the branch coating material paths is provided. Thus, it is possible to prevent external air from entering the nozzle head, and the coating material from leaking to the outside of the nozzle head.
