METHOD FOR MANUFACTURING OPTICAL MEMBER AND MANUFACTURING DEVICE

To provide a method for manufacturing an optical member with less powdery substances such as grinding dust attached thereto, and a manufacturing device.SOLUTION: A method for manufacturing an optical member includes the steps of: preparing a laminated body 100 having an optical film 50 and an adhesive layer 80 disposed on one surface of the optical film 50, the laminate body having an end surface E with powdery substances f attached; and removing the powdery substances f from the end surface E by hitting dry ice particles d to the end surface E of the laminated body 100. The laminated body 100 has a hole H penetrating through in a thickness direction of the optical film 50 as well as the adhesive layer 80, and the end surface E serves as an inner surface of the hole H.SELECTED DRAWING: Figure 3 【課題】研磨屑などの粉体の付着が少ない光学部材の製造方法及び製造装置を提供する。【解決手段】光学部材の製造方法は、光学フィルム５０、及び、光学フィルム５０の一方の面に設けられた粘着剤層８０を有し、その端面Ｅに粉体ｆが付着している積層体１００を準備する工程と、積層体１００の端面Ｅにドライアイス粒子ｄを衝突させて端面Ｅから粉体ｆを除去する工程と、を含み、積層体１００は、光学フィルム５０及び粘着剤層８０の厚み方向に貫通するホールＨを有し、端面Ｅが、ホールＨの内壁である。【選択図】図３
