The liquid supplied to an emitter electrode located at a tip of an atomization nozzle receives the high-voltage and electrically charged. The mist of the charged minute water particles of nanometer sizes is generated from the emitter electrode. A pressure regulating means regulates a pressure applied to the liquid on the tip of the emitter electrode. Therefore, the mode of generating the mist of the charged minute water particles of nanometer sizes or the mode of generating the mist of the charged minute water particles of nanometer and micron size is selected.

An electrostatic atomizing device for ejecting a mist of charged minute particles includes metal ion elution means for eluting sterilizing metal ions into a liquid to be electrostatically atomized. The metal ions are taken up by the charged minute particles, and are ejected into an environment space together with the charged minute particles, thereby eliciting a sterilizing effect. The elution amount of the metal ions is regulated by varying the voltage applied between two kinds of metal bodies.
