Patent ID: 7665829

Claim:
A liquid ejecting apparatus, which ejects droplets of electrically charged liquid solution onto a base member, comprising: a liquid ejecting head to eject the droplets from a top portion of a nozzle; a liquid solution supplying section to supply the liquid solution to the nozzle; and an ejection voltage applying section to apply an ejection voltage to the liquid solution in the nozzle; and an opposed electrode which is provided opposing to the nozzle through the base member; wherein the liquid ejecting head comprises a nozzle plate having a nozzle plane which is opposed to the base member, and the nozzle arranged on the nozzle plate, and a liquid solution chamber provided on the opposite side of the nozzle plate to the nozzle plane side, an inside diameter of the nozzle being equal to or less than 100 μm; and wherein the nozzle is protruded from a nozzle plane in an ejecting direction of the droplets and a protruded height of the nozzle is equal to or less than 30 μm, a length of a flow channel formed in the protruded part of the nozzle and through the nozzle plate reaching to the liquid solution chamber is equal to or greater than 75 μm, and electric conductivity of a material structuring the nozzle is equal to or less than 10 −13 S/m.
