Abstract
An electrostatic suction type fluid discharge device supplies a drive voltage from a power source between a nozzle and an insulating substrate, so as to supply an electric charge to a discharge material supplied into the nozzle. As a result, the discharge material is discharged from the nozzle hole onto the insulating substrate. The diameter of the hole of the nozzle falls within the range between φ0.01 μm and φ25 μm, the power source outputs, as the drive voltage, a bipolar pulse voltage that alternates between positive and negative and has a frequency of not less than 1 Hz.
