Electrostatic atomization device

An electrostatic atomization device that electrostatically atomizes condensed water and emits atomized water. The electrostatic atomization device includes a discharge electrode. A water supplier unit includes a cooling unit coupled to the discharge electrode to cool the discharge electrode and a heat radiation unit coupled to the cooling unit to emit heat when the cooling unit performs cooling. The cooling unit cools air and produces condensed water on the discharge electrode. A controller includes electronic components mounted on a circuit board. A casing accommodates the discharge electrode, the water supplier unit, and the controller. First electronic components each of which temperature is increased by a predetermined value or greater are arranged in a heat radiation unit side region of the circuit board.
