Abstract
In one example embodiment, a substrate having a smooth surface is prepared, a fine-particle layer including fine particles which are arranged along the surface is formed, and substituent molecules are bonded to the fine particles to change the fine-particle layer to a fine-particle assembly layer including the fine particles to which the substituent molecules are bonded, so that the center-to-center distance between the adjacent fine particles is increased to form a three-dimensional microstructure in which a portion of the fine-particle assembly layer is raised from the surface or the center-to-center distance between the adjacent fine particles is decreased to form a microstructure in which the fine-particle assembly layer is absent in a portion of the surface, the substrate being exposed in the absent portion.
