Abstract
A method for fabricating a water-repellent surface, including steps of preparing a mixture by mixing a curable liquid with a needle-like material, applying the mixture onto a surface of an object, curing a liquid of the applied mixture and forming an applied layer in which the needle-like material has been mixed on a base material of the cured liquid of the mixture, forming pits and projections of the needle-like material on a surface of the applied layer by etching the applied layer under a condition where an etching rate of the base material is larger than that of the needle-like material, and coating the surface of the applied layer with a water-repellent substance.
