METHOD FOR PRODUCING LIQUID-EJECTION HEAD

摘要

A liquid-ejection head including:
a substrate on or above which a plurality of actuators are formed, the plurality of actuators generating energy for ejecting a liquid; anda flow-passage-forming member on or above the substrate, the flow-passage-forming member defining ejection ports through which the liquid is ejected and a plurality of liquid chambers each having a corresponding one of the plurality of actuators,the flow-passage-forming member including an orifice plate defining the ejection ports and liquid-chamber side walls defining side walls of the plurality of liquid chambers,the flow-passage-forming member being formed of an inorganic material and having a depressed portion between the liquid chambers, and the depressed portion being filled with a photosensitive resin.
