Abstract
The repellency increasing structure includes a substrate, if a surface of the substrate is flat, a flat surface of which shows lyophilic property with respect to a liquid having a surface tension lower than that of water and multiple recesses multiple and/or projections that are formed in the surface of the substrate. Inner walls of the recesses and outer walls of the projections are substantially parallel to a thickness direction of the substrate. The structure further includes a repellent layer that covers the recesses and the projections. In the liquid ejection head, a solution ejection surface around multiple through-holes of a ejection substrate corresponds to the surface of the substrate of the repellency increasing structure in which the recesses and/or the projections are formed. In the stain-resistant film, the substrate of the repellency increasing structure is a support film.
