description The present invention provides a method for producing a laminated film suitable for producing a large-sized laminated film having a soft adhesive layer at high efficiency. The producing method according to the present invention comprises a preparation step and an outer shape machining step. In the preparation step, a long strip workpiece film W sequentially having a carrying film C, a film layer 10, an original adhesive layer 20, and a film layer 30 in the thickness direction H is prepared. In the outer shape machining step, the workpiece film W is irradiated with laser beam from the film layer 30 side by a laser machining device having a plurality of galvanometer scanners S while the workpiece film W is enabled to move along a flowing direction D1. The original adhesive layer 20 and the film layer 30 are cut on the film layer 10. In the step, the scanning regions R having the same quantity as that of the galvanometer scanners S correspond to the galvanometer scanners S one to one. Each galvanometer scanner S
