PROBLEM TO BE SOLVED: To provide a light antireflection article improving a streaky defect 3 caused by strings of internal air bubbles G numerously aligned in one direction, inside an antireflection layer having a light antireflection structure composed of numerous minute projections.SOLUTION: In an antireflection article 10, an antireflection layer 2 having numerous minute projections 2t is laminated in a belt-like manner on a surface of a curable resin layer 2r, making contact with a belt-like transparent base material 1. The minute projections form an antireflection structure that satisfies: maximum interval Pmax=Pave+3&sgr;≤λmax=maximum wavelength of visible light wavelength band area 780nm, with regard to an average value Pave of intervals P between highest protrusions thereof and a standard deviation &sgr;. An inner area of at least 8 W/10 of the antireflection layer is defined by removing areas of maximum W/10 from both ends in width direction with regard to a layer width W in width direction perpendicular to a longer direction of the antireflection layer. The inner area includes no streaky defects 3 caused by strings of internal air bubbles G whose size is 5 μm or larger aligned in plurality in the longer direction. |
