    摘要: An aspect of the present invention is a process for producing a liquid ejection head including an ejection orifice member provided with ejection orifices for ejecting liquid. The process includes supplying to a surface of a base material for forming the ejection orifice member a mixture of a first composite for imparting a hydrophobic characteristic to the surface and a second composite being able to exhibit a hydrophilic characteristic by being irradiated with light; imparting a hydrophobic characteristic to the entire or a part of the surface by utilizing the first composite; and then irradiating the second composite with light in a partial region of the surface for imparting a hydrophilic characteristic to the region irradiated with the light.
