    摘要: Provided are a method for three-dimensionally molding a film, a method for manufacturing a film molded body, and a film molded body that make it possible to easily perform three-dimensional molding of an inner film portion while achieving a reduction in processing time and a decrease in energy consumption and without requiring a design change to the existing equipment. A method for three-dimensionally molding a film, the method including performing cold compression molding in a thickness direction on a film overlapping section 50 in which at least one inner film portion 20 including a first layer 21 and a second layer 22 having an elongation smaller than that of the first layer is arranged between two outer film portions 30 in a non-fixed state with respect to the outer film portions 30, thereby causing the inner film portion 20 to protrude toward the second layer 22 side at the film overlapping section 50.
