In a method of manufacturing a microstructure, an aluminum member having an aluminum substrate and a micropore-bearing anodized layer present on a surface of the aluminum substrate is subjected at least to, in order, a pore-ordering treatment which involves performing one or more cycles of a step that includes a first film dissolution treatment for dissolving 0.001 to 20 wt % of a material constituting the anodized layer and an anodizing treatment which follows the first film dissolution treatment; and a second film dissolution treatment for dissolving the anodized layer, thereby obtaining the microstructure having micropores formed on a surface thereof. This method enables a microstructure having an ordered array of pits to be obtained in a short period of time.
