Zusammenfassung:	A method for producing a multilayer optical film according to one embodiment of the present invention is a method for producing a multilayer optical film 1 wherein a second optical film (20) is bonded to a first optical film (10). This method for producing a multilayer optical film 1 comprises: a curl adjustment step wherein a film for curl adjustment (12) is bonded to the first optical film by a film bonding device (40) so that a curl of the first optical film is reduced by a curl applied by the film bonding device in a predetermined direction, thereby obtaining a first multilayer film; and a bonding step wherein the first multilayer film and the second optical film are bonded with each other by the film bonding device so that the first optical axis (SA) of the first optical film and the second optical axis (SD) of the second optical film are at a predetermined angle [theta], thereby obtaining a second multilayer film, namely the multilayer optical film 1.
