PROBLEM TO BE SOLVED: To provide a three-dimensional molding method of a laminated film body capable of obtaining a practical projection amount without being restricted by a material constitution of the laminated film, and without generating a crack or rupture.SOLUTION: A laminated film body 1 comprising an inner film 11 having at least a large elongation of the innermost surface, and a film 12 having a small elongation on the outer surface side, is subjected to cold multi-stage compression molding, while increasing successively the amount of compression to an original thickness of the laminated film body, to thereby project a compression molding part to the outer surface side.SELECTED DRAWING: Figure 2 |
