An electrostatic atomizer requiring no water tank and capable of exhibiting an electrostatic atomization effect instantaneously. The electrostatic atomizer comprises a discharge electrode, a counter electrode facing the discharge electrode, a unit for supplying water onto the discharge electrode, and a high voltage source for applying a high voltage between the discharge electrode and the counter electrode. Water on the discharge electrode is electrostatically charged by applying a high voltage, and fine particles of charged water are emitted from the discharge end at the forward end of the discharge electrode. The water supply unit is so structured as to condense water in the surrounding air on the discharge electrode, and water can be supplied onto the discharge electrode in a short time without utilizing an extra water tank. Consequently, fine particles of charged water can be atomized immediately upon use of the atomizer. |
