A droplet jetting apparatus using a nano-tip is provided to jet a fluid in the form of droplet without the thermal change by applying an adjustable electrostatic field onto the fluid surface. A droplet jetting apparatus comprises a body part(100) equipped with a cantilever(140), a horizontal open channel(150), a vertical open channel(160), and a first electrode(110), a second electrode(120) installed between a pointed end(144a) of a nano-tip(144) and prints(A) and having a through hole(120h) through which the droplets of fluid are emitted toward one-side surface of the prints, a power supply part(200) applying a voltage between the first and the second electrode, a third electrode(130) which is located apart from the other-side surface of the prints, and a controller(300) controlling the power supply part.
