<p>The purpose of the present invention is to provide a fine-unevenness transfer mould with which defect regions of a moulded body having a fine-unevenness structure can be easily identified, and deformation of the fine-unevenness structure can be inhibited even if the moulded product is wound. A mould used in the production of an optical article having, provided to a surface thereof, a plurality a protruded portions at a cycle equal to or less than the wavelengths of visible light, and a plurality of recessed portions formed between the adjacent protruded portions, is characterized by having, provided to a surface thereof, a transfer area in which recessed portions and protruded portions are provided, said recessed portions and protruded portions having a size and shape that complement the protruded portions and the recessed portions of the optical article. The mould is further characterized in that, in the transfer area, marking portions are provided, and the height of the protruded portions in the transfer area is less than the height of protruded portions in sections other than the transfer area.</p> |
