Abstract
A method for producing a liquid discharging recording head including an ink discharge opening, an ink supply opening, an ink channel communicating with the ink discharge opening and the ink supply opening, and an energy generating element provided corresponding to the ink channel and adapted for generating energy to be utilized for ink discharge comprises the steps of: PA0 forming a first photosensitive material layer for ink channel formation, on a substrate bearing thereon the energy generating element; PA0 pattern exposing the first photosensitive material layer for forming the ink channel; PA0 forming a second photosensitive material layer on the first photosensitive material layer; PA0 pattern exposing the second photosensitive material layer for forming the ink discharge opening and the ink supply opening; and PA0 developing the first and the second layers of photosensitive materials.
