<P>PROBLEM TO BE SOLVED: To provide a manufacturing method and a manufacturing device capable of cutting out an optical laminated sheet by a knife edge without disrupting the posture of the optical laminated sheet, whose interlayers are not bonded. Ž<P>SOLUTION: A conveying body 35 having the blanked optical laminated sheet 21 is passed between a support roller 50 and a retaining roller 52, then wound around a turnaround roller 51 which has a slightly changed traveling direction to the conveying body 35, and conveyed. The optical laminated sheet 21 is cut off from the conveying body 35 at the vicinity of an exit of the support roller 50 which has a slightly changed traveling direction to the conveying body 35. Cutting of the laminated sheet 21 is performed while a deformation amount generated by the difference between outer and inner circumferences of the laminated sheet 21 wound on the support roller is kept minimum by keeping the change of the traveling directions small. The laminated sheet 21 can be easily retrieved as the winding angle becomes larger, so that the posture of the laminated sheet 21 is not disrupted and the optical laminated sheet 21 can be stably cut.
