PURPOSE: A nozzle using electrostatic force for a droplet spraying device is provided to minimize a size of the liquid surface because the liquid surface is pinned by forming edges of a feeding unit on a rim of a spraying plane. CONSTITUTION: A nozzle using electrostatic force for a droplet spraying device comprises a feeding unit(110) and a spraying plane(120). The feeding unit is formed towards a liquid supply direction. At least one edge is formed on the rim of the end portion ejecting the supplied liquid. The spraying plane is extended in a vertical direction to a liquid supply direction from the rim of the end portion of the feeding unit ejecting liquid in order that the ejecting liquid can form a liquid surface. |
