PROBLEM TO BE SOLVED: To provide a decorative film for film insert molding whose peak-and-valley pattern is not crushed during molding and which does not cause crack even when the film is subjected to deep drawing, and to provide a method of producing same.SOLUTION: The resin-made decorative film is used for giving a peak-and-valley pattern on the surface of a molded article in film insert molding. The decorative film 1 for film insert molding is composed of: a shaping layer film 2 on which the peak-and-valley pattern is formed; and a protective layer film 3 tightly adhering to the uneven pattern. Here, the adhesion between the shaping layer film 2 and the protective layer film 3 is weak.
