A stretchable wiring film includes: (A) a stretchable film made of, at least as a top surface of the stretchable film, a cured product of a stretchable film material containing a silicone polyurethane resin; and (B) a stretchable wiring. The top surface of the stretchable film has a repeated uneven pattern formed with depths of 0.1 μm to 5 mm and pitches of 0.1 μm to 10 mm. The stretchable wiring is formed on the top surface of the stretchable film where the repeated uneven pattern is formed. Thus, the present invention provides: a stretchable wiring film having less decrease in electric conductivity in stretching and excellent water repellency on the film top surface; and a method for forming the stretchable wiring film.
