To provide a manufacturing method of an uneven pattern film with good flatness and with less spots when arranging a reflection preventing layer on a formed uneven pattern film by which a uniform uneven pattern can be obtained in continuous production.
In the manufacturing method of the uneven pattern film forming the uneven pattern on the transparent resin film using an emboss roll having unevenness in its surface, the transparent resin film comes in contact with a crown roll arranged in direct front of the emboss roll, thereafter an ultraviolet curing resin composition is introduced between the transparent resin film wound around the emboss roll and the emboss roll, ultraviolet light is irradiated to from the inside of the emboss roll, thereafter the ultraviolet cured resin layer on whose surface unevenness is formed is peeled from the emboss roll together with the transparent resin film.
