Abstract:
1. A method of manufacturing an ink-jet recording head, comprising the steps of: preparing a base plate having an ink ejection pressure generating element and a liquid path pattern, which is removable, located on a part of the base plate that includes the ink ejection pressure generating element; applying a first active energy setting material on the base plate and the liquid path pattern; applying an ink-repellent second active energy setting material, which is dry, on the first active energy setting material before exposing the first active energy setting material; forming an image pattern of an ejection port for ejecting ink, which image pattern is the same in both the first active energy setting material and the ink-repellent second active energy setting material, by exposing both the first active energy setting material and the ink-repellent second active energy setting material in a process by applying light to both the first active energy setting material and the ink-repellent second active energy setting material simultaneously through a mask corresponding to the ejection port for ejecting ink; and developing the image pattern formed in the preceding step in the first active energy setting material and the ink-repellent second active energy setting material so as to form the ejection port above the ink ejection pressure generating element.
