To provide a decorative film whereby formation of wrinkles is suppressed when attached to a three dimensional molded product in a stretched state, and a method for producing a decorative film-attached three dimensional molded product. The decorative film of the present invention is a decorative film having at least a base film and a top layer containing a fluorinated polymer, the top layer being disposed on one surface, wherein the surface reflection intensity Wa at a wavelength of from 0.1 to 0.3 mm and the surface reflection intensity Wb at a wavelength of from 0.3 to 1.0 mm, of the top layer as measured by using a wave scan apparatus in such a state that the decorative film is stretched by 1.5 times, are both at most 30.0.
