A method of manufacturing a microstructure. While pressing a first pattern of a first mold against a first transferred resin layer obtained by applying a first photocurable resin composition on a transparent base having a light shielding pattern, a first cured resin layer with the first pattern transferred thereto is formed by irradiating the first transferred resin layer with an activation energy line through the first mold; While pressing a second pattern of a second mold against a second transferred resin layer obtained by applying a second photocurable resin composition on the first cured resin layer, a second cured resin layer is formed having a level difference shape including a lower level area and a higher level area by irradiating the second transferred resin layer with an activation energy line using the light shielding pattern as a mask to cure the second transferred resin layer in a partial region.
