Method for producing optical laminate with adhesive layer having through-hole

The invention provides a method for simply and inexpensively manufacturing an optical laminate with an adhesive layer having through-holes in which lack of glue and embossment of a surface protection film and a separator are suppressed. A method of manufacturing an optical laminate with an adhesive layer having a through hole according to an embodiment of the present invention comprises: forming a workpiece by laminating a plurality of optical laminates with adhesive layers; and forming a through hole at a predetermined position of the workpiece by cutting using the end mill. The optical laminate with an adhesive layer includes an optical film, an adhesive layer disposed on one side of the optical film, a separator temporarily bonded to the adhesive layer in a peelable manner, and a surface protective film temporarily bonded to the other side of the optical film in a peelable manner. The formation of the through-hole includes cutting by moving the end mill upward or downward while making the end mill abut aga
