Method for manufacturing machined optical laminate with attached adhesive layer

The present invention provides a method which enables easy and low-cost manufacture of a machined optical laminate with an attached adhesive layer, whereby separation defects in a surface protection film are minimized. This method for manufacturing a machined optical laminate with an attached adhesive layer involves: forming a workpiece by layering a plurality of sheets of the optical laminate with an attached adhesive layer; and machining the outer peripheral surface of the workpiece using an end mill having a helical cutting edge. The optical laminate with an attached adhesive layer comprises an optical film, an adhesive layer disposed on one side of the optical film, a separator temporarily attached to the adhesive layer in a separable manner, and a surface protection film temporarily attached to the other side of the optical film in a separable manner. In this manufacturing method, the workpiece is formed by layering the optical laminate with an attached adhesive layer such that the separator is positione
