To provide an electrostatic atomization device rapidly and surely introducing water fed from a water feed part to a tip end atomizing part of a water application electrode, stably providing a large amount of electrostatic mist, and settable in a space of a small depth.

The electrostatic atomization device includes the water feed part and the water application electrode atomizing the water at the tip end atomizing part by receiving the water fed from the water feed part and applying high voltage, and forms electrostatic mist. The water feed part includes a Peltier unit, a heat radiation part 7 in contact with a heat radiation face thereof, and a cooling part 8 in contact with a cooling face located on the reverse side of the heat radiation face and forming dew condensation water to be water fed to the water application electrode. The heat radiation part 7 is opened at the upstream side to the passing air flow, and the cooling part 8 is restricted in the passing air volume by an air volume adjusting part 61 provided in upstream side of the passing air flow.
