Abstract

An electrostatic atomization device (1) provided with a transformer including primary and secondary coils (5a, 5b). A switching element (6) is connected in series to the primary coil. A switching element drive circuit (8) provides the switching element with a pulse signal to perform a switching operation and generate high voltage from the secondary coil. A discharge unit including a discharge electrode (3, 4) performs electrostatic atomization on liquid supplied to the discharge electrode to generate charged fine liquid droplets when high voltage generated by the secondary coil is applied to the discharge electrode. The switching element drive circuit generates a pulse signal having an oscillation frequency set so that the transformer has drooping characteristics that prevent air discharge from occurring between the discharge electrode and ground even when load on the discharge unit varies and prevents the generation of ozone having a predetermined concentration or greater when the liquid undergoes electrostatic atomization.
