Abstract:
A manufacturing method of an ink-jet recording head including ejection ports formed by using a resin layer and a water-repellent photosensitive resin layer, wherein both resins are curable by irradiating with an energy active ray, comprising steps of:preparing a substrate having ink ejecting energy generating portions, forming said resin layer on the substrate, curing said resin layer, except portions disposed at said ejection ports and at the periphery of said ejection ports, by irradiating with said energy active ray, forming said water-repellent photosensitive resin layer on said cured resin layer, curing said water-repellent photosensitive resin layer and nonirradiated portions of said resin layer, except for portions disposed at said ejection ports, simultaneously by irradiating with said energy active ray, forming said ejection ports by developing said resin layer and said water-repellent photosensitive resin layer.
