  • Patent number: 10099232
    Abstract: An electrostatic atomizing device of the present disclosure includes a discharge electrode, a counter electrode, a liquid supplying unit, a current path, a voltage applicator, and a limiting resistor. The limiting resistor is disposed on a first current path or a second current path included in the current path. The first current path electrically connects the voltage applicator and the counter electrode, and the second current path electrically connects the voltage applicator and the discharge electrode. This makes it possible to increase an amount of generated radicals while keeping an increase of ozone small. In addition, an electric current peak of an instantaneous electric current can be kept small.
