PROBLEM TO BE SOLVED: To provide a winding method of a laminated film capable of suitably manufacturing a winding roll of a high winding quality by suitably restraining the occurrence of winding wrinkle out and blocking. SOLUTION: While applying static tension to the other end by fixing one end of a test piece of the laminated film while horizontally restricting the movement in the horizontal direction of the test piece of the laminated film, correlation data between an elongation and tension on the test piece of its laminated film is obtained, and next, a reference elongation of the test piece of the laminated film is set, and next, the tension in the reference elongation is calculated from the correlation data, and the tension for winding the laminated film is calculated and set based on the tension in its reference elongation.
