摘要：
A method for producing a film having a fine irregular pattern intermittently includes feeding a film to be processed intermittently from upstream side to the vicinity of the surface of a die having a fine irregular pattern, transferring the pattern to the surface of the film by pressing the film against the surface of a die, stripping the processed film on which a pattern is formed from the surface of a die, and then feeding a new film to be processed to the die, wherein the processed film is stripped from the surface of a die by gripping and moving the processed film to the upstream side, and then the processed film is fed by a length of intermittent feed to the surface of a die while preventing the processed film from creasing.
