A laminated glass, a method for producing a laminated glass, and a reflective film that has end parts where the generation of wrinkles is prevented in a case where the laminated glass is produced by sandwiching the reflective film between two glass plates and that has a reflection wavelength range with a small variation are provided. The reflective film has wavelength-selective reflectivity. A thermal shrinkage rate in a case where the reflective film is held at 140°C for 30 minutes is greater than 0.5% and smaller than 2.0%. The reflective film has at least one cutout portion on a side edge of the reflective film.
