Abstract:
An electrostatic atomizer (100) includes a guard electrode (4) between an opening (11) and an opening (12). The guard electrode (4) is different from a spray electrode (1) and a reference electrode (2). A voltage between the spray electrode (1) or the reference electrode (2) and the guard electrode (4) is controlled to have a magnitude within a prescribed range smaller than a magnitude of a voltage between the spray electrode (1) and the reference electrode (2).
