A hydrophobic liquid containing a dispersion medium and fine particles is prepared. The fine particles have insolubility of a certain level in a predetermined liquid having a hydrophobic character. The hydrophobic liquid is applied to a support to be a film thereon. Wet gas is blown to the film. Water vapor is condensed from ambient air on a surface of the film to generate water drops thereon. A dispersion medium evaporating gas is blown to the film, such that the dispersion medium is evaporated from the film. A water drop evaporating gas is blown to the film, such that the water drops are evaporated from the film. Accordingly, the water drops function as the template for forming pores, such that the pores are formed on a micro protrusion-depression structure constituted by the fine particles.
