Abstract: A liquid ejection head is manufactured by forming a dent representing a substantially spherical profile so as to include a position for forming an ejection port on a surface of a photosensitive resin layer, then forming a latent image of the ejection port in the dent by an exposure treatment using a projection lens system, and developing the latent image. The center of the top surface of the latent image is shifted to the incoming side of the beam of exposure light from the lowest point of the dent.
