The present invention relates to a microstructure 20 having pores 22 on its surface or inside. The microstructure is a sheet containing an energy ray active resin 21. The pores 22 are formed in a vertical array and are in a formation pattern with a Talbot distance being specified by Formula 1 below:

Z.sub.T=(2nd.sup.2)/λ  [Formula 1] where Z.sub.T represents a Talbot distance (nm), n represents a refractive index, d represents a pitch distance (nm), and λ represents a light wavelength (nm). The pores have a periodic shape in the planar direction. Thus, the present invention provides three-dimensional microfabricated structures through which the periodicity is controlled.
