Abstract
The present invention provides a droplet jetting apparatus which jets fluid in a droplet shape. The apparatus includes a main body (100), which has a chamber (110) for containing fluid. The main body further has at least one nozzle (120) which communicates with the chamber and jets a droplet onto a printable matter, and a first electrode (130) which is formed on the inner surface of at least one selected from between the nozzle and the chamber by patterning treatment to make electrical contact with the fluid. The apparatus further includes a second electrode (140), which is provided between the nozzle and the printable matter and has a through hole, through which the droplet is jetted from the nozzle onto the printable matter, a power supply (200) which supplies a voltage applied between the first electrode and the second electrode, and a control unit (300) which controls the power supply.
