PROBLEM TO BE SOLVED: To provide an adhesion strength evaluating method for quantitatively evaluating the adhesion properties at the interface of a laminated film in a short time. SOLUTION: In the method of evaluating the adhesion strength of the laminated film for evaluating the adhesion strength at the interface of the upper layer and lower layer of the laminated film with at least the upper layer and the lower layer, the laminated film is fixed on a stage, a blade is pressed to the upper layer of the cross section of the laminated film and relatively moved in one direction so as to become parallel to the surface of the laminated film to peel off the upper layer of the laminated film, the load values applied to the blade during the period from the point of time when the blade is pressed to the cross section of the laminated film to the point of time when the upper layer of the laminated film is peeled off are measured and the maximum load value is set as the adhesion strength.
