Abstract
An electrostatic suction type fluid discharge method and device include a voltage applying means that applies a pulse voltage between a nozzle and a substrate, the nozzle having a diameter ranging from 0.01 μm to 25 μm, an upper limit voltage of the pulse voltage being equal to or greater than a discharge-inducing minimum voltage. A lower limit first voltage can be provided immediately before a rise of the pulse voltage, an absolute value of the lower limit first voltage being set smaller than the discharge-inducing minimum voltage. A lower limit second voltage can be provided immediately after a rise of the pulse voltage, an absolute value of the lower limit second voltage being set smaller than the discharge-inducing minimum voltage. With this structure, it is possible to simultaneously achieve miniaturization of nozzle, discharge of micro fluid droplet, high accuracy for discharge position, and decrease in drive voltage.
