Liquid ejection head and process for producing the same |
摘要 |
<p>Provided is a process for producing a liquid ejection head including an ejection orifice member having a plurality of ejection orifices for ejecting liquid provided along an arrangement direction, the process including preparing a substrate provided with a resin layer which contains a photocurable resin;carrying out a first exposure treatment and a second exposure treatment which are each of an exposure treatment of subjecting the resin layer to exposure; and forming the ejection orifices of the resin layer subjected to the first exposure treatment and the second exposure treatment. An inclination angle of a side wall of the ejection orifices formed by the first exposure treatment with respect to the substrate differs from an inclination angle of a side wall of the ejection orifices formed by the second exposure treatment with respect to the substrate.</p> |
