A method capable of easily producing a nanostructured material having regular nanoscale arrangement. The method comprises a raw material solution preparation step of preparing a raw material solution by dissolving, in a solvent, a block copolymer comprising a polymer block component "A" and a polymer block component "B" which are immiscible to each other, and an inorganic precursor which coordinates with the polymer block component "A" but does not coordinate with the polymer block component "B"; and a nanostructure-forming step of forming a nanophase-separated structure "10" in which a polymer phase "1A" comprising the polymer block component "A" with which the inorganic precursor is coordinated, and a polymer phase "1B" comprising the polymer block component "B" are regularly arranged by self-assembly. A nanostructured material can be obtained by this method. Moreover, by converting the inorganic precursor to an inorganic component, it is possible to obtain an organic/inorganic nanostructured material "20" comprising a polymer phase "2A" containing the inorganic component and a polymer phase "1B". Furthermore, by removing the organic component, it is also possible to obtain an inorganic nanostructured material "30".
