Liquid ejection head and method of manufacturing the same
Abstract:
A liquid ejection head for an electrostatic ink jet including an insulating ejection substrate in which through holes are bored to form ejection openings for ejecting droplets; an insulating support substrate arranged while facing the ejection substrate with a predetermined distance therebetween; a solution flow path provided between the ejection substrate and the support substrate; ejection electrodes, respectively provided corresponding to the through holes, for exerting electrostatic forces on the solution; and a shield electrode, provided corresponding to at least one of the through holes on a solution ejection side with respect to the ejection electrodes, for preventing electric field interferences between the through holes. Plural flow path wall portions contacting the ejection substrate stands in the solution flow path, and at least one of electrode lines connected to the ejection electrodes and electrode lines connected to the shield electrode are contained in the flow path wall portions.
