A method for producing an ink jet recording head comprising the following steps, a step which forms the photosensitive water-repellent processing layer in the ink discharge port face, a step which irradiates light onto the water-repellent forming region and hydrophilic forming region in the water-repellent processing layer, to cure the layer, a step which irradiates light selectively onto the hydrophilic forming region to reduce water repellency of the water-repellent processing layer and to impart hydrophilicity to the hydrophilic forming region, and a step which forms an opening, which constitutes part of the ink discharge port, in the water-repellent processing layer.
