PROBLEM TO BE SOLVED: To correct a defect of a molding die which causes deterioration of an antireflection function of micro projections related to a moth-eye structure of an antireflection article, and poor appearance.;SOLUTION: In a method for correcting a roll plate 13 which is a method for correcting the roll plate 13 molding micro projections 5 of an antireflection article 1, the roll plate 13 includes a base material 13a, an adhesion layer 13b formed on the surface of the base material 13a, and a molding layer 13c that is provided on the surface side of the base material 13a through the adhesion layer 13b, and has fine uneven shapes molding the micro projections 5 formed on the surface of the antireflection article 1. The method for correcting the roll plate 13 includes: a defect determination step of detecting the surface shape of the molding layer 13c, and determining whether a portion projecting from the surface of the roll plate 13 corresponds to a defect or not based on the detected content; and a defect correcting step of correcting the defect determined in the defect determination step. The defect determination step determines the defect based on an outer dimension of the portion projecting from the surface of the roll plate 13.;COPYRIGHT: (C)2014,JPO&INPIT
