LIQUID EJECTION HEAD, LIQUID EJECTOR AND LIQUID EJECTING METHOD

摘要

A liquid ejection head having a flat ejection face and capable of forming a micro pattern and ejecting high viscosity liquid by application of a low voltage using electrostatic attraction type liquid ejection technology, a liquid ejector and a liquid ejecting method employing them. A liquid ejection head (2) comprises a nozzle (10) for ejecting a liquid L, a flat nozzle plate (11), a cavity (21) for storing the liquid L ejected from an ejection hole (13) of the nozzle (10), an electrostatic voltage applying means (19) for applying an electrostatic voltage between the liquid L in the nozzle (10) and the cavity (21) and a substrate K to generate electrostatic attraction, and an operation control means (23) for controlling application of the electrostatic voltage by the electrostatic voltage applying means (19), and is characterized in that the nozzle plate (11) has a volume resistivity of 10<SUP>15</SUP> Om or more.
