The producing method includes: (I) providing an active energy ray curable resin composition for mold surface release treatment between a mold having uneven microstructure on its surface and a substrate, and after curing the resin composition by irradiation with an active energy ray, peeling off the substrate together with a cured article of the active energy ray curable resin composition from the surface of the mold, thereby performing a release treatment to the surface of the mold; and (II), after step (I), providing an active energy ray curable resin composition for shaping between the substrate and the mold, the surface of which has been treated by the release treatment, and after curing the resin composition by an active energy ray, peeling off the substrate together with a cured article of the active energy ray curable resin composition for shaping from the surface of the mold.
