ABSTRACT:
The liquid repellent structure includes a support, and a honeycomb-patterned film and a coating film on the honeycomb-patterned film or a liquid repellent film. The method of producing the structure applies a solution of an organic compound in an organic solvent onto the support, places the support in an atmosphere containing water vapor to form water droplets on a surface of the solution film, evaporates the organic solvent and the droplets to form the honeycomb-patterned film, and forms the coating film made of a fluorine-containing material on a surface of the honeycomb-patterned film or etches the honeycomb-patterned film to form a second honeycomb-patterned film. The liquid ejection head includes an ejection substrate having the liquid repellent structure. The protective film includes a support base and the liquid repellent structure.
